The influence of oxygen partial pressure on material properties of Eu3+-doped Y2O2S thin film deposited by Pulsed Laser Deposition.

Abdub, Guyo Ali; Swart, H. C.; Dejene, Francis (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 ...
Synthesis and characterization of Y2O3:Eu3+ phosphors using the Sol-Combustion method.

Abdub, Guyo Ali; Swart, H. C.; Dejene, Francis (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 ...
Temperature dependence of structural and luminescence properties of Eu3+-doped Y2O3 red-emitting phosphor thin films by pulsed laser deposition.

Abdub, Guyo Ali; Swart, H. C.; Dejene, Francis (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 ...
