Effect of thickness on optical properties of nickel vertical posts deposited by GLAD technique
(Optical Materials, 2016)
Nickel (Ni) thin films of different thicknesses (25 nm to 150 nm) were deposited on glass substrates using Glancing Angle Deposition technique. Characterization of obtained Ni films was performed by scanning electron ...
Europium-doped nanocrystalline Y2O3 - La2O3 solid solutions with bixbyite structure
(Journal of Physics and Chemistry of Solids, 2014)
Nanocrystals of Y2O3 and La2O3 solid solutions were synthesized with a cubic bixbyite structure containing La2O3 content of up to 50 mol%. This is comparatively higher than that in bulk materials of the same structure, ...
Synthesis and luminescent properties of rare earth (Sm3+ and Eu3+) Doped Gd2Ti2O7 pyrochlore nanopowders
(Optical Materials, 2014)
This work describes the synthesis and photoluminescent properties of rare earth (Sm3+ and Eu3+) doped Gd2Ti2O7 pyrochlore nanopowders. Pure-phase rare earth-doped Gd2Ti2O7 nanoparticles of approximately 20-50 nm in diameter, ...
Far-infrared spectra of mesoporous ZnS nanoparticles
(Optical Materials, 2016)
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 ...
Hydrothermal synthesis of Li4Ti5O12/C nanostructured composites: Morphology and electrochemical performance
(Materials Research Bulletin, 2013)
Li4Ti5O12/C composites with low (3 wt.%) and high (33 wt.%) carbon black content as well as carbon-free Li4Ti5O12 were prepared in two steps under identical conditions: hydrothermal reaction at 130 degrees C and post-calcination ...
Comparative structural and photoluminescent study of Eu3+-doped La2O3 and La(OH)(3) nanocrystalline powders
(Journal of Physics and Chemistry of Solids, 2014)
Eu3+-doped La2O3 nanocrystalline powder was prepared by polymer complex solution method and further used for preparation of Eu3+-doped La(OH)(3). Structural and optical characterization was carried out by powder X-ray ...
Improved efficiency of sol-gel synthesized mesoporous anatase nanopowders in photocatalytic degradation of metoprolol
(Materials Research Bulletin, 2013)
The structural and morphological properties of mesoporous anatase nanopowders, synthesized by sol-gel method, have been modified by varying the duration of calcination, in order to obtain more efficient photocatalyst than ...
Formation of ZnIn2S4 nanosheets and tubular structures in organic media
(Materials Research Bulletin, 2017)
Hot-injection method for synthesis of ZnIn2S4 (ZIS) in organic media was studied. Nanosized ZnIn2S4 is successfully synthesized in oleic acid/oleylamine mixture in different ratios, which are both: complexing and/or capping ...
Graphene quantum dots and fullerenol as new carbon sources for single-layer and bi-layer graphene synthesis by rapid thermal annealing method
(Materials Research Bulletin, 2017)
Graphene as a new material is in the spotlight due to its extraordinary properties and wide range of potential applications. Chemical vapour deposition, as a method for graphene synthesis from gaseous hydrocarbon sources ...
Enhancing photoluminescence of graphene quantum dots by thermal annealing of the graphite precursor
(Materials Research Bulletin, 2017)
Different approaches for enhancement of the graphene quantum dots (GQDs) photoluminescence have been developed lately. We report modified electrochemical procedure for GQDs synthesis. Graphitic rods were thermal annealing ...
