报道了用层间反应法制备ＣａＧａ２Ｓ４∶Ｃｅ薄膜，用电子束蒸发法交替沉积ＣａＳ∶Ｃｅ和Ｇａ２Ｓ３膜，然后经一定的处理，获得ＣａＧａ２Ｓ４∶Ｃｅ膜。Ｘ射线衍射、ＳＴＥＭ显微照片和ＥＤＸ等分析结果表明，产物为结晶度较好、符合ＣａＧａ２Ｓ４∶Ｃｅ化学计量比的发光薄膜，并得到了Ｃｅ３＋的蓝色发光谱。
It is reported that the CaGa2S4: Ce film is prepared by the interlayer reaction method, and the CaS: Ce and Ga2S3 films are alternately deposited by the electron beam evaporation method, and then the CaGa2S4: Ce film is obtained through a certain treatment. X-ray diffraction, STEM micrographs and EDX analysis results show that the product is a good crystallinity, in line with CaGa2S4: Ce stoichiometric light-emitting film, and obtained the blue emission spectrum of Ce3.
