Incoherent emission
WebAug 18, 2024 · Incoherent cathodoluminescence emission occurs when the material is excited with an electron beam, where the primary electrons decelerate and deposit energy into the material. An important property of incoherent CL is that there is no fixed phase relation between a photon that is emitted and incoming excitation electron. This CL type …
