We report a portable rare-earth element analyzer with a palm-top size chamber including the electron source of a pyroelectric crystal and the sample stage utilizing cathodoluminescence (CL) phenomenon. The portable rare-earth element analyzer utilizing CL phenomenon is the smallest reported so far. The portable rare-earth element analyzer detected the rare-earth elements Dy, Tb, Er, and Sm of ppm order in zircon, which were not detected by scanning electron microscopy-energy dispersive X-ray spectroscopy analysis. We also performed an elemental mapping of rare-earth elements by capturing a CL image using CCD camera.
我们报告了一种便携式稀土元素分析仪，其具有掌上型尺寸的腔室，包括热释电晶体电子源和利用阴极发光（CL）现象的样品台。利用CL现象的便携式稀土元素分析仪是迄今为止报道的最小的此类仪器。该便携式稀土元素分析仪检测到了锆石中ppm级的稀土元素镝（Dy）、铽（Tb）、铒（Er）和钐（Sm），而扫描电子显微镜-能量色散X射线光谱分析未检测到这些元素。我们还通过使用电荷耦合器件（CCD）相机捕获CL图像，对稀土元素进行了元素映射。
