摘　　要：介绍了利用化学溶液沉积法将ZnS:Cu,Pb,Mn材料制成红外上转换薄膜的工艺过程。利用金相显微镜和扫描电子显微镜观察了薄膜表面形貌,并测试了薄膜的荧光光谱、荧光激发光谱、红外激励发光光谱、红外激励光谱和红外激励发光衰减曲线。测试结果显示:成膜质量良好;薄膜的激发光谱位于450 nm以下的紫外及可见光区域;红外响应光谱范围为700～1500 nm;荧光光谱及红外激励发光光谱上均有位于490 nm和580 nm的峰值;红外激励发光衰减先快后慢,能持续较长时间。The paper introduced the process of fabricating infrared up-conversion thin film from the material ZnS： Cu, Pb, Mn via the chemical solution deposition technique. The surface morphology of the thin film was observed with metallographic microscope and scanning electron microscope. Fluorescence spectrum, fluorescence excitation spectrum, infrared stimulated luminescence spectrum, infrared stimulation spectrum and infrared stimulated luminescence decay curve were measured. The results shown that, the thin film is superior in surface quality. The excitation spectrum of the thin film is from UV to 450 nm visible light. The IR sensitivity spectrum is in the range of 700-1500 nm. Both the fluorescence spectrum and the infrared stimulated luminescence spectrum have two peaks corresponding to 490 nm and 580 nm. The infrared stimulated luminescence decayed rapidly at the beginning, then decayed slowly and persisted for a long time.
