Application of Cathodoluminescence in Gemstone Identification

Yuhan Ma

Abstract


According to the different colors, luminous intensity and images presented by gemstones under cathodoluminescence, it can be used
to understand the structure of gemstones, including the lattice defects they have, to quickly and nondestructively identify the species of gemstones, to identify the types, valence and quantities of trace elements in them, and to explore the environment of crystal growth and the conditions of formation.
