Abstract

Eu2+-activated RbBaScSiO glass phosphor was synthesized by a melt synthesis technique using arc-imaging furnace and their photoluminescence properties were characterized. In addition, the obtained glass phosphors annealed in a flow of 5%H295% Ar gas to enhance the luminescent efficiency. The emission spectra of the Eu2+-activated glass phosphors presents yellow emission band centered at 537nm due to the 4f65d 1→ 4f7 transition of Eu2+, and the emission intensity was effectively enhanced by the annealing treatment.
