Abstract

The high Luminance electroluminescent (EL) device having excellent color coordinates were developed. A CaAl_2S_4:Eu phosphor exhibited the purest green photoluminescence among Eu^<2+> ion doped IIa-IIIb_2-S_4 group phosphors. CaAl_2S_4:Eu EL devices were prepared by the two target pulsed-electron-beam evaporation method. The maximum luminance level under 1 kHz sinusoidal wave voltages was over 4,000 cd/m^2. Commission Interantionale de 1'Eclairage (CIE) color coordinates were x=0.121, y=0.670.
