Abstract

Mn^<2+> doped ZnAl_2S_4 and MgAl_2S_4 phosphors for electroluminescent devices were investigated. These phosphors showed orange emission with the peak at 600 nm and 605 nm, respectively. MgAl_2S_4:Mn^<2+> thin films were prepared by two-target pulsed evaporation technique. Substrate temperature and post-annealing condition for MgAl_2S_4:Mn^<2+> films were explored. MgAl_2S_4:Mn^<2+> electroluminescent devices showed orange emission and the CIE color coordinate is (x=0.584, y=0.410). Maximum luminance was 118 cd/m^2 under 1 kHz sinusoidal wave voltage.
