本文综述了阴极发光显微镜和光谱学在矿物和材料研究中的应用。CL既可以用于纯粹描述性的方式，通过不同的CL颜色来检测和区分不同的矿物或矿物世代，也可以作为一种有效的方法，通过光谱CL测量对固体中的点缺陷进行空间分辨分析。阴极发光发射在所有情况下都与晶格缺陷（例如断键上的电子缺陷、空位或辐射诱导缺陷）和/或痕量激活离子（如REE2+/3+、Fe3+、Cr3+、Al3+、Mn2+、Pb2+、Cu2+、Sn2+或铀酰基）有关。CL光谱是表征材料纯度或检测天然和合成矿物中微量元素的杰出方法。通过这种方法，即使在具有异质织构和非晶相含量高的材料中，也可以成功地检测到微量元素的变化、扩散或新相的形成。
The present study summarizes results of cathodoluminescence (CL) microscopy and spectroscopy applied to minerals and materials. CL can be used both in a purely descriptive way to detect and distinguish different minerals or mineral generations by their variable CL colours or as an effective method for spatially resolved analysis of point defects in solids by spectral CL measurements. The cathodoluminescence emission is in all cases either related to lattice defects (e.g. electron defects on broken bonds, vacancies or radiation induced defects) and/or to trace activator ions such as REE2+/3+, Fe3+, Cr3+, Al3+, Mn2+, Pb2+, Cu2+, Sn2+ or uranyl groups. CL spectroscopy is an outstanding method to characterize the degree of purity of materials or to detect trace elements in natural and synthetic minerals. In this way, alterations, diffusion of trace elements or formation of new phases are successfully detectable even in the case of materials with heterogeneous texture and high contents of non-crystalline phases.
