Preparation of SrGa_2S_4:Ce thin films has been carried out by the multi-source deposition technique and it's structural and lIuminescent properties were characterized. The thin films show blue emission with good chromaticity. The dependence of the Iuminescence on Ga_2S_3/Sr flux ratio and annealing conditions were investigated, The film prepared at Ga_2S_3/Sr flux ratios of 60, and annealed at 850℃ showed high luminance with CIE co-ordinates of(0.11, 0.10). However these films were showing different PL and CL spectra. Results are discussed on the formation process of SrGa_2S_4 and it's luminescent property depending on the annealing atmosphere.
