Abstract
Preparation of SrGa_2S_4 : Ce thin films showing blue-emission with good chromaticity has been carries out by the multi-source deposition technique, then the structural and luminescent properties of the films were characterized. I this experiment, the dependence of the properties on Ga_2S_3/Sr flux ratio and annealing conditions was investigated. The film prepared at CeCl_3/Sr and Ga_2S_3/Sr flux ratios of 0.03 and 60, respectively, and annealed at 850℃ in Ar showed a luminance of about 1000cd/cm^2 and CIE coordinates of (0.11, 0.098).
