초록
Phosphors of Eu2+ doped alkaline earth aluminates MAl2O4:Eu2+ (M=Sr, Ba, Ca) have been prepared by sol-gel process and their characterization of photoluminescence and photocurrent properties have been performed. The phosphors prepared by sol-gel process, due to its advantage of better homogeneity and low synthetic temperature, was synthesized as single phases at lower temperature than the solid-state process; 800~1000 oC for 6 h under mild reduction atmosphere (Ar- 3% H2). It was confirmed that SrAl2O4:Eu2+ composition revealed the most excellent properties in the brightness and photocurrent.
