AB  - In the present work experimental study of the ZnO@ZnS core-shell nanostructure with an active layer obtained by conversion of zinc oxide powders with H2S is reported. Тhe prepared structures were characterized by scanning electron microscopy, X-ray diffraction, Raman spectroscopy, and far-infrared spectroscopy. Top surface optical phonon (TSO) in ZnO, characteristic for the cylindrical nano-objects, the surface optical phonon (SOP) mode of ZnS, and SOP modes in ZnO@ZnS core-shell nanostructure are registered. Local mode of oxygen in ZnS and gap mode of sulfur in ZnO are also registered. This result is due to the existence of an active layer in the space between ZnO core and ZnS shell, which is very important for the application of these materials as thermoelectrics. © 2020 John Wiley & Sons, Ltd.

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. 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  - 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  - The nanocomposite consisting of PbS quantum dots with average diameter of 26 A and polyvinyl alcohol was characterized using photoluminescence and far-infrared spectroscopy. Photoluminescence spectra of nanocomposite, measured in temperature range from 8 to 280 K, consists of broad peak which spans the energy range from 1.2 to 2.1 eV and can be connected with trap states inside the band gap. Far-infrared measurements are consistent with theoretical calculations that include mechanical boundary conditions at the quantum dot - host interface. Observed peak at 90 cm(-1) can be assigned to coupled modes with l(p) = 1, while broad peak at 275 cm(-1) is above any lattice frequency and is close to sum of the frequencies of the l(p) = 0 acoustic and l(p) = 0 coupled optical mode of PbS quantum dots.

AB  - A nanocomposite consisting of lead sulfide (PbS) nanoparticles (NPs) with average diameter of 26 angstrom, according to absorption threshold shift, and polyvinyl alcohol (PVA) was characterized using far-infrared absorption spectroscopy. The experimental results are consistent with theoretical calculations that include proper mechanical boundary conditions at the nanocrystal-host interface.
