Incoherent emission

WebFor an incoherent mechanism, it is defined as that "the intensity (or luminosity) of radiation from the source is less or equal to the sum of the intensities of spontaneous emission from different parts of the source" and as "due to spontaneous emission when the corresponding absorption process is unimportant" . From these definitions, we come ... 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 …
