AB  - The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic material, ZnS, has the cubic structure and its crystallite size was estimated to be 2.3 nm, which implies that a strong confinement regime is in effect. Analysis of Raman spectra was performed using the fitting procedure based on effective medium theory. As a result, the surface optical phonon (SOP) mode was detected. It was found that the shape and position of the SOP mode depend on the type of the composite. © 2019 Elsevier B.V.

AB  - In this paper, we describe synthesis and characterization of YVO 4 and Eu 3+ -doped YVO 4 nanopowders. Two methods of preparation were used—solution combustion synthesis (SCS) and classical ceramic method (CCM)—and compared. Morphology and structure of all samples were characterized with atomic-force microscopy (AFM), X-ray diffraction (XRD), and field-emission scanning electron microscopy (SEM). Raman spectroscopy was used to discuss the isotope-like effect. It is confirmed that doping with Eu ions results in a change of Raman spectra of doped samples—new modes arise, and intensity of existing ones change. Influence of different preparation methods on isotope-like effect is presented with detailed calculations of shifted modes. © 2019 John Wiley & Sons, Ltd.

AB  - The phase changes of MnO nanoparticles under laser-induced heating have been studied. Previous confirmation of the existence of MnO phase was based on the X-ray diffraction measurements. Here, we report the experimental spectra of nonresonant Raman scattering in the range between 100 and 1,600cm(-1), for a sample irradiated with 8 different laser powers. The laser-induced heating has produced change in existing phases in sample, destruction of MnO phase, and creation of MnO2, Mn3O4, and MnOOH phases along with formation of Mn2+ on the sample surface. These phase changes have been confirmed by X-ray diffraction and atomic force microscopy measurements.

In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. This study reports investigation of the effects of using different solvents and polymers in preparation of BGO composite on the microstructural and optical behaviour of the resulting material. Preparation of such composites by a solution casting method is described. Poly (methyl methacrylate) (PMMA) and polystyrene (PS)) were used as matrix materials and acetone and chloroform as solvents. Their microstructure and the quality of BGO dispersion and deaggregation in polymer matrix were analyzed by SEM, Raman, XRD and optical spectroscopy. The influence of particle size distribution, their shapes, and concentration on the optical transmission is calculated based on Mie scattering theory and discussed, too. (C) 2016 Elsevier B.V.

AB  - This paper describes the structural and optical properties of Cu-Se thin films. The surface morphology of thin films was investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). Formation of Cu-Se thin films is concluded to proceed unevenly, in the form of islands which later grew into agglomerates. The structural characterization of Cu-Se thin film was investigated using X-ray diffraction pattern (XRD). The presence of two-phase system is observed. One is the solid solution of Cu in Se and the other is low-pressure modification of CuSe2. The Raman spectroscopy was used to identify and quantify the individual phases present in the Cu-Se films. Red shift and asymmetry of Raman mode characteristic for CuSe2 enable us to estimate nanocrystal dimension. In the analysis of the far infrared reflection spectra, numerical model for calculating the reflectivity coefficient of layered system, which includes film with nanocrystalite inclusions (modeled by Maxwell -Garnett approximation) and substrate, has been applied.

AB  - ZnS nanoparticles were synthesized mechanochemically by high-energy milling, with three different milling times (5 min, 10 min and 20 min). Nitrogen adsorption method was used for examining specific surface area and texture of obtained powders. It was found that all samples are completely mesoporous. The optical properties were studied by far-infrared spectroscopy at room temperature in spectral region of 50-600 cm(-1). The analysis of the far-infrared reflectivity spectra was made by the fitting procedure. The dielectric function of ZnS nanoparticles is modeled as a mixture of homogenous spherical inclusions in air by the Maxwell-Garnet formula. In the analysis of the far-infrared reflection spectra, appearance of combined plasmon-LO phonon modes (CPPMs) with high phonon damping are observed, which causes decrease of coupled plasmon-phonon frequencies.

AB  - ZnS nanoparticles were synthesized mechanochemically by high-energy milling. In order to investigate influence off milling time to sample properties, samples were produced in three different milling times (5 min, 10 min and 20 min). The morphology of samples has been investigated by scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). X-ray diffraction (XRD) investigation of synthesized nanocrystals identified cubic structure. From XRD, ZnS size of crystallites was estimated as 1.9 nm (after 5 min milling time), 2.3 nm (10 min) and 2.4 nm (20 min), implying that we are in strong confinement regime. The optical properties were studied by Raman spectroscopy, in spectral region 100-500 cm(-1), excitation source was 514.5 nm (E-L = 2.41 eV), which means that we are in off resonant regime. Dominant spectral structures, of comparable intensity, are registered in spectral region 130-180 cm(-1), around 265 cm(-1) and around 345 cm(-1). First two are assigned as second-order ZnS modes. A theoretical model of continuum medium was used to calculate frequencies of the confined optical phonons in ZnS. Satisfactory agreement with experimental results was found and mode at 345 cm(-)1 is assigned as LO type phonon confined in ZnS nanocrystal. (C) 2015 Elsevier B.V. All rights reserved.

AB  - Our work deals with the problem of producing a complex metal-ceramic composite using the processes of internal oxidation (IO) and severe plastic deformation. For this purpose, Cu-Al alloy with 0.4wt.% of Al was used. IO of sample serves in the first step of the processing as a means for attaining a fine dispersion of nanosized oxide particles in the metal matrix. Production technology continues with repeated application of severe plastic deformation (SPD) of the resulting metal-matrix composite to produce the bulk nanoscaled structural material. SPD was carried out with equal channel angular pressing (ECAP), which allowed that the material could be subjected to an intense plastic strain through simple shear. Microstructural characteristics of one phase and multiphase material was studied on internally oxidized Cu with 0.4wt.% of Al sample composed of one phase copper-aluminum solid solution in the core and fine dispersed oxide particles in the same matrix in the mantle region. In this manner AFM, X-ray diffraction and Raman spectroscopy were used. Local structures in plastically deformed samples reflect presence of Cu, CuO, Cu2O, Cu4O3 or Al2O3 structural characteristics, depending on type of sample.

AB  - Nickel ferrite, NiFe2O4 has been prepared by a soft mechanochemical route from mixture of (1) Ni(OH)(2) and alpha-Fe2O3 and (2) Ni(OH)(2) and Fe(OH)(3) powders in a planetary ball mill for varying duration. Soft mechanochemical reaction leading to formation of the NiFe2O4 spinel phase was followed by X-ray diffraction, Raman and infrared spectroscopy, TGA, scanning and transmission microscopy. The spinel phase formation was first observed after 4 h of milling and its formation was completed after 25 h in the both cases. The synthesized NiFe2O4 ferrite has a nanocrystalline structure with a crystallite size of about 20 and 10 nm respectively for the cases (1) and (2). The final grain size in the system (1) is about twice as large as that in the system (2), what is a consequence of different reaction paths in these two processing routes. There are five Raman and four IR active modes. Mossbauer spectroscopy studies implied on the possible cation distribution between the tetrahedral and octahedral sites in formed NiFe2O4 spinel structure. We were able to estimate the degree of inversion at most 0.82 in the case (1) and 0.66 in the case (2). (c) 2012 Elsevier Ltd. All rights reserved.

AB  - Bi12GeO20 single crystals were grown by the Czochralski technique. The critical diameter and the critical rate of rotation were calculated. Suitable polishing and etching solutions were determined. As a result of our experiments, the pale yellow and black single crystals were produced. The structure of the Bi12GeO20 has been investigated by X-ray diffraction, Raman and IR spectroscopy. The atomic ratio Bi/Ge was determined for the both crystals. The refractive indexes of both Bi12GeO20 crystals were determined by the spectroscopic ellipsometry method. Important properties of Bi12GeO20 for sensing applications, optical activity, Faraday rotation and absorption were measured and magneto optical quality was calculated and compared.

AB  - Far-infrared reflectivity spectra, in spectral region 50-600 cm(-1) and temperature region 80-300 K, of CdS and Cd1-xMnxS nanocrystals embedded in hexametaphosphate, are presented. The analysis of the far-infrared experimental reflectivity spectrum was made by the fitting procedure. The Maxwell-Garnet effective medium theory is used for modeling an effective dielectric function as well as to separate respond from nanoparticles. To analyze spectra in CdS omega(TO)(approximate to 238 cm(-1)) to omega(TO)(approximate to 305 cm(-1)) spectral region, quantized dipolar modes in a spherical isotropic material quantum dot (QD) are considered in the framework of a continuum model. As to the mechanical boundary conditions rigid sphere is concerned. Experimental far-infrared reflectivity spectra of our samples are in general agreement with the predictions of this model. Experimentally registered and through fitting procedure located features for CdS nanoparticles in spectral region below CdS omega(TO) at: approximate to 102 cm(-1), approximate to 135 cm(-1), approximate to 170 cm(-1) and approximate to 210 cm(-1) are associated to defect induced modes, especially to defects located near the surface of CdS QD. In region over CdS omega(LO), modes are identified as multiphonons. In Cd1-xMnxS QD spectra new reflectivity peaks are at: approximate to 85 cm(-1), approximate to 110 cm(-1) and approximate to 180 cm(-1) in spectral region below CdS omega(TO), approximate to 270 cm(-1) inside CdS omega(TO)-omega(LO) spectral region and approximate to 356 cm(-1) and approximate to 376 cm(-1) in region over CdS omega(LO). First two registered modes are associated to both mass and force constant defects at the surface, and rest four modes are consequence of MnS phases present in the sample.

AB  - Manganese ferrite, MnFe2O4 have been prepared by a soft mechanochemical route from mixture of (a) Mn(OH)(2) and alpha-Fe2O3 and (b) Mn(OH)(2) and Fe(OH)(3) powders in a planetary ball mill. The mixture was activated for varying duration. Soft mechanochemical reaction leading to formation of the MnFe2O4 spinel phase was followed by X-ray diffraction, Raman spectroscopy, scanning and transmission microscopy and magnetization measurements. The spinel phase formation was first observed after 12 h of milling and its formation was completed after 25 h in both cases. The synthesized MnFe2O4 ferrite has a nanocrystalline structure with a crystallite size of about 40 and 50 nm respectively for cases (a) and (b). There are five Raman active modes. Measurements after 25 h of milling show magnetization values of 70.4 emu/g and 71.1 emu/g respectively for cases (a) and (b). In order to understand better the whole process of phase formation, Mossbauer measurements were done. (C) 2011 Elsevier B.V. All rights reserved.

AB  - Bismuth titanate, Bi4Ti3O12 powders were prepared by mechanically assisted synthesis from their oxides. The diameter of obtained particles depends on time of milling. In order to understand the grain size effects on the crystal structure we measured X-ray, TEM analysis and Raman spectra. The effect of mechanical treatment on the grain size is quite evident: as the milling time increases (3, 6, 12 h), the powder becomes more activated and grain size decrease (7.3, 7.2, 6.9 nm). With reducing the grain size, quantum effects at the Raman spectra, is reflected in the mode position change against balk crystal. And also, coagulation of each line appears, as well as a significant asymmetry of certain modes. (c) 2006 Elsevier B.V. All rights reserved.

The effect of mechanical treatment on the grain size is quite evident: as the milling time increases (3, 6, 12 h), the powder becomes more activated and grain size decrease (7.3, 7.2, 6.9 nm). With reducing the grain size, quantum effects at the Raman spectra, is reflected in the mode position change against balk crystal. And also, coagulation of each line appears, as well as a significant asymmetry of certain modes. (c) 2006 Elsevier B.V. All rights reserved.",

AB  - The formation of amorphous carbon nitride under bombardment of fullerene thin films by single and multiple charged nitrogen ions is presented in this paper. The characterization of a new amorphous carbon nitride phase was performed by Raman, Fourier transform infrared spectroscopy, low angle x-ray diffraction and UV/Vis spectrophotometry. The structural modification in fullerene films after bombardment by single and multiple charged nitrogen ions has been examined by atomic force microscopy. It was found that the surface ordering has been changed significantly depending on the charge of the used ions. The optical band gap was found to be varied from 1.7 to 1.3 eV for bombarded films by N5+ ions and 1.4 eV for irradiated films by N+ ions.

The properties of as-deposited and irraditated fullerene thin films have been investigated by Raman and FTIR spectroscopy and AFM analysis. After irradiation by multiple charged nitrogen ions (N(2+), N(5+)) new bondings in fullerene films have been formed and the amorphicity has been enhanced at higher doses. Raman and FTIR spectra showed structural changes of deposited films depending on the energy and implantation dose. AFM analysis showed that the ion beam had destroyed the surface ordering. At lower doses the surface order has been characterized by carbon clusters of 500 nm. At higher doses significantly smaller clusters have been formed (200 nm).

Cd1-xMnxS nanoparticles have been synthesized by using aqueous solution precipitation. We obtained interesting features in FIR spectra: there are expected modes of bulk US (240 cm(-1), 300 cm(-1)), new modes connected with namo-size of US (130 cm(-1), 170 cm(-1)) and additional mode at 120 cm(-1) in Cd1-xMnxS nanoparticles which can be assigned to the presence of Mn. The position of obtained modes is discussed in the frame of the linear chain model with both mass and force constant defects. Raman spectroscopy gives us only the mode at 300 cm(-1) and its second harmonic.

AB  - Far-infrared reflectivity spectra of Hg1-xMnxTe1-ySey (0.01 and LE; x and LE; 0.14, 0.01 and LE; y and LE; 0.1) single crystals were measured in the 80-420cm(-1) range at room temperature. The analysis of the far-infrared spectra was made by a fitting procedure based on the model of coupled oscillators. The dependence of plasma frequency and phonon modes on composition was determined. A model for phonon behavior in quaternary mixed crystals of the type A(1-x)B(x)C(1-y)D(y) was developed, too. This model was tested for Hg1-xMnxTe1-ySey. and COPY; 2004 Elsevier B.V.

abstract = "Far-infrared reflectivity spectra of Hg1-xMnxTe1-ySey (0.01 and LE; x and LE; 0.14, 0.01 and LE; y and LE; 0.1) single crystals were measured in the 80-420cm(-1) range at room temperature. The analysis of the far-infrared spectra was made by a fitting procedure based on the model of coupled oscillators. The dependence of plasma frequency and phonon modes on composition was determined. A model for phonon behavior in quaternary mixed crystals of the type A(1-x)B(x)C(1-y)D(y) was developed, too. This model was tested for Hg1-xMnxTe1-ySey. and COPY; 2004 Elsevier B.V.
