Application of Cathodoluminescence Microscopy and
Basics of Luminescence and Instrumentation. In general luminescence is the transformation of diverse kinds of energy into visible light. It results from an emission transition of anions molecules or a crystal from excited electronic states to the ground state or a state with lower energy (Marfunin Reference Marfunin 1979).The whole process includes three fundamental stages (1) absorption

Cathodoluminescence fundamentals Delmic
· Cathodoluminescence is most commonly performed in a scanning electron microscope. In a vacuum chamber containing the sample of interest an electron beam is focused on the sample. The light which is generated then has to be collected with a collection optic (e.g. mirror or objective) or directly captured by a CL detector in the chamber.

What is Cathodoluminescence Cathodoluminescence
· Cold-cathode CL (as opposed to hot ) is the most commonly used optical-CL system. It is attached to a microscope so that any lumincescent response can be viewed through an objective lens and then recorded with a digital camera. Phosphorescence is when radiation continues after the incident energy source is turned o˚ (continues to
