OPO laser light absorption and evolutionary behaviour of SWCNT thin films
(Journal of Optoelectronics and Advanced Materials, 2012)
In this paper we report a systematic study on the properties of irradiated SWCNT films by high power, pulsed visible irradiation of OPO laser in the range from 430 nm to 800 nm. Raman analysis showed that metallic and ...
Analysis of SiO2 thin film deposited by reactive sputtering
(Materials Science Forum, 2006)
SiO2 layers were deposited by reactive d.c ion sputtering (using 1 keV Ar+ ion gun) from a high purity silicon target in an oxygen ambient. The base pressure in the deposition chamber was 4.7-10(-9) mbar, and the substrate ...
Gallium doping influence on optical and transport properties of PbTe
(Materials Science Forum, 2000)
Zn this work we used far-infrared and Raman spectroscopy for investigation of gallium doping influence on optical and transport properties of PbTe. We focused our interest to fortify the correlation between local modes and ...
Preparation and characterization of spinel nickel ferrite obtained by the soft mechanochemically assisted synthesis
(Materials Research Bulletin, 2013)
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 ...
Characterization of partially inverse spinel ZnFe2O4 with high saturation magnetization synthesized via soft mechanochemically assisted route
(Journal of Physics and Chemistry of Solids, 2014)
ZnFe2O4 was prepared by a soft mechanochemical route from two starting combinations of powders: (1) Zn(OH)(2)/alpha-Fe2O3 and (2) Zn(OH)(2)/Fe(OH)(3) mixed in a planetary ball mill. The mechanochemical treatment provoked ...
Cd1-xMnxS nanoparticles: Far-infrared phonon spectroscopy
(Materials Science Forum, 2005)
Phonon spectra of Cd1-xMnxS (x = 0; 0.01; 0.05; 0.1; 0.15; 0.3) nanoparticles (d similar to 4.5 rim) have been investigated by far-infrared reflection (FIR) (spectral range 40 - 600 cm(-1), temperature range 80-300 K) and ...
Comparative study on modification of single wall carbon nanotubes by sodium dodecylbenzene sulfonate and melamine sulfonate superplasticiser
(Applied Surface Science, 2009)
In this work, the results of synthesis and characterization of single wall carbon nanotubes (SWCNTs) functionalized by two surfactants (sodium dodecylbenzene sulfonate and melamine sulfonate superplasticiser) have been ...
Surface chemical modification of fullerene by mechanochemical treatment
(Applied Surface Science, 2009)
In this study different encapsulating agents have been used for chemical modi. cation of fullerenes. Fullerenes have reacted with tetrahydrofuran, sodium dodecyl sulfate, sodium dodecylbenzene sulfonate and ethylene vinyl ...
Comparison of structural properties of pristine and gamma irradiated single-wall carbon nanotubes: Effects of medium and irradiation dose
(Materials Characterization, 2012)
A systematic study of the gamma irradiation effects on single wall carbon nanotube (SWCNT) structure was conducted. Nanotubes were exposed to different doses of gamma irradiation in three media. Irradiation was carried out ...
Gamma ray-assisted irradiation of few-layer graphene films: a Raman spectroscopy study
(Physica Scripta, 2014)
This paper represents results of a Raman spectroscopy study of gamma-irradiated few-layer graphene thin films at three different doses: 25, 50 and 110 kGy. Graphene thin films were deposited by the vacuum filtration method ...
