激光剥蚀电感耦合等离子体质谱法分析Cr∶ZnSe晶体中掺杂元素Cr的含量和分布
采用激光剥蚀电感耦合等离子体质谱(LA-ICP-MS)法研究激光晶体材料Cr∶Zn Se晶体中掺杂元素铬(Cr)的含量和分布。利用镀膜扩散掺杂方法,制备不同掺杂浓度的Cr∶Zn Se晶体标准样品作为固体标准物质,实现Cr∶Zn Se晶体中Cr的定量分析。LA-ICP-MS法研究自制标准样品中Cr的分布均匀性,电感耦合等离子体光谱法测定其准确含量。通过激光点剥蚀和线扫描剥蚀采样,获得Cr元素的点位和含量分布信息,实现晶体中Cr的原位微区分析。标准工作曲线相关系数0.9992,检出限0.08 mg/kg。本方法可为不同生长条件下Cr∶Zn Se晶体中Cr的统计分布分析提供有效检测手段。...

Several different Cr : ZnSe crystals were prepared by diffusion method as reference material to solve the problem of accurate quantization. The homogeneity of Cr in these samples was characterized by LA-ICP-MS and the concentrations achieved by inductively coupled plasma atomic emission spectrometry (ICP-AES). With signal pot and line scan sampling, the present method provided effective position and content distribution information of Cr in ZnSe crystals, achieved the in |
