Optical properties of ZnO nanoparticles synthesized by varying the sodium hydroxide to zinc acetate molar ratios using a Sol-Gel process.
(Springer, 2016)Material property dependence on the OH−/Zn2+ molar ratio of the precursor was investigated by varying the amount of NaOH during synthesis of ZnO. It was necessary to control the water content and temperature of the mixture ... -
The influence of oxygen partial pressure on material properties of Eu3+-doped Y2O2S thin film deposited by Pulsed Laser Deposition.
(Elsevier B.V., 2015)Eu3+-doping has been of interest to improve the luminescent characteristics of thin-film phosphors. Y2O2S:Eu3+ films have been grown on Si (100) substrates by using a Pulsed Laser Deposition technique.The thin films grown ... -
Temperature dependence of structural and luminescence properties of Eu3+-doped Y2O3 red-emitting phosphor thin films by pulsed laser deposition.
(Springer, 2016-02)Pulse laser deposition was used to obtain nanocrystalline red-emitting Y2O3:Eu3+ thin-film phosphors.X-ray diffraction measurements show that the un-annealed thin film was amorphous, while those annealed were crystalline.At ... -
Synthesis and characterization of Y2O3:Eu3+ phosphors using the Sol-Combustion method.
(Elsevier B.V., 2014)Y2O3: Eu3+ phosphor powders were prepared by the Sol-Combustion synthesis method using a sulfur-contained organic fuel in an ethanol–aqueous solution. The structural, morphological and optical properties of the as-prepared ... -
The influence of different species of gases on the luminescent and structural properties of pulsed laser-ablated Y2O2S:Eu3+ thin films.
(Springer., 2016-04)Y2O2S:Eu3+ films have been grown on Si (100) substrates by using a pulsed laser deposition technique. The thin films grown under vacuum, argon and oxygen ambient have been characterized using structural and luminescent ... -
Wide visible emission and narrowing band gap in Cd-doped ZnO nanopowders synthesized via sol-gel route.
(Elsevier Ltd., 2016)Cd doped ZnO nanopowder (Zn1−XCdXO, 0.15≤ X ≤0.45) has been synthesized by facile sol-gel method. The X-ray diffraction (XRD) shows the powder possess polycrystalline with hexagonal wurtzite structure of ZnO without formation ... -
Narrow Visible Emission And Narrowing Band Gap In Ho3+ -Co Doped Y2O3: Eu3+ Nanopowders Prepared Via Sol- Combustion Route.
(IOSR Journal of Applied Physics, 2017-12)Nanocrystalline Eu3+, Ho3+co-doped Y2O3 powders with a maximum size of 9.8 nm were prepared by the sol-combustion process, using Y (NO3).6HO2 as an oxidizer, europium and holonium nitrates as activators, thiourea as a fuel ... -
Effect of Mn doping on the structural and optical properties of sol-gel derived ZnO nanoparticles.
(Springer, 2011)Un-doped and Mn-doped ZnO nanoparticles were successfully synthesized in an ethanolic solution by using a sol-gel method. Material properties of the samples dependence on preparation conditions and Mn concentrations were ... -
