Abstract
SrGa_2S_4 : Ce films for blue-emitting thin-film electroluminescent devices have been prepared by multi-source deposition. Sr, Ga_2S_3 and CeCl_3 were used as source materials. It was found that the annealing in H_2S atmosphere was considerably effective for the improvement of the crystallinity and luminescent properties of the SrGa_2S_4 : Ce thin films. The SrGa_2S_4 : Ce film that was annealed at best anneal condition of 800℃ for 1〜2 hours in H_2S showed strong blue PL and CL with CIE coordinate of (0.12,0,10).
