Abstract

A $Eu^{2+}$ doped $BaAl_2S_4$ phosphor was synthesized from BaS, EuS, Al and S powder by vacuum heat treatment. The synthesized powder at $850^{\circ}C$ was composed of only $BaAl_2S_4$ phase. The photoluminescence of $Eu^{2+}$ doped $BaAl_2S_4$ phosphor showed the blue emission centered at 470nm and CIE color coordinate at x=0.12, y=0.11.
