Eu2+-activated Rb-Ba-Sc-Si-O 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%H2-95%Ar gas to enhance the luminescent efficiency. The excitation spectra of the Eu2+-activated glass phosphors are consisted of broad band covering the region from 220 to 450 nm, and presents yellow emission band centered at 537 nm due to the 4f65d1 → 4f7 transition of Eu2+. These results indicate that Eu2+-activated Rb-Ba-Sc-Si-O glass phosphors are a suitable candidate for the yellow-emitting phosphor of near UV based white LEDs lamps. |
