Synthesis of Eu2+-activated Rb–Ba–Sc–Si–O glass phosphors using melt synthesis technique

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 emi...

description	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 emission spectra of the Eu2+-activated glass phosphors presents yellow emission band centered at 537 nm due to the 4f65d1 → 4f7 transition of Eu2+, and the emission intensity was effectively enhanced by the annealing treatment.
