Abstract

Phosphors of $Eu^{2+}$ doped alkaline earth aluminates MA$l_2O_4:Eu^{2+}$ (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; $800{\sim}1000{^{\circ}C}$ for 6 h under mild reduction atmosphere (Ar- 3% $H_2$). It was confirmed that SrA$l_2O_4:Eu^{2+}$ composition revealed the most excellent properties in the brightness and photocurrent.
