【摘要】 采用碳还原法制备了电子俘获材料 CaS：Eu,Sm,研究了灼烧温度及灼烧时间对样品发光性能的影响。XRD 测试表明,样品具有 CaS 的面心立方结构,晶格常数为0．58nm。样品的激发谱峰值在279、 466、497nm 处,荧光光谱的峰值在649nm 处,光激励发光峰为650nm,光激励发光的光谱响应范围为900～ 1400nm。更多还原

【Abstract】 CaS:Eu,sm was prepared by carbon reduction method.The effect of calcination temperature and time on luminescence intensity of sample was studied.XRD patterns indicated that the samples prepared were with face-center cubic structure and the lattice parameter was 0.58nm.Excitation spectrum peaking of sample was at 279,466 and 497nm. The peaking of fluorescence spectrum was at 649nm.The photo-stimulation luminescence spectrum peaking was at 650nm.The wavelength response range of the photo-stimulation luminescence is located at 900-1400nm.更多还原
