1	What is Cathodoluminescence “CL” Electron bombardment of materials can cause emission of light. This is known as Cathodoluminescence “CL”. Present day examples are televisions, computer terminals, plasma displays, oscilloscopes and electron microscope fluorescent screens. With the developments of electron optical instruments in recent decades, CL has become an an important characterization technique for the analysis of materials which luminesce.
