摘要
采用稀土直接掺杂工艺提高了电子俘获材料ＣａＳ∶Ｅｕ，Ｓｍ和ＣａＳ∶Ｃｅ，Ｓｍ的发光亮度和制备效率，并利用超短脉冲红外激光测试了它们的红外上转换效率借助等离子体质谱技术检测了硫化助熔剂法和稀土直接掺杂工艺合成电子俘获材料中主要掺杂剂的化学计量比。
The luminance and the productivity of synthesizing ETM, such as CaS∶Eu,Sm and CaS:Ce,Sm, have been risen greatly by utilizing the rare earth direct doped technique, their infrared upconversion efficiency is obtained by using the ultrashort infrared pulse from a pulsed CPM Nd∶YAG laser. Prepared by sulfurizing flux method and the rare earth direct doped technique, stoichiometry of the major activators in ETM is measured by means of ICP MS. The main factors influencing upconversion efficiency of ETM are analyzed.
