CL (Cathodoluminescence) spectroscopy

Cathodoluminescence (CL) spectroscopy is a technique used to study materials by shining a focused electron beam onto them. When electrons hit the material, they excite its atoms, causing them to emit light. By analyzing this emitted light, scientists can learn about the material’s composition, structure, and electronic properties at a very small scale. CL is especially useful in examining minerals, semiconductors, and nanomaterials, helping researchers understand their features and how they might be used in electronics, lighting, and other applications.
