| Popis | Cathodoluminescence (CL) is an opto-electronic phenomenon of a large number of solids, when an incident electron beam causes the light emission. This phenomenon is widely utilized in electron beam instruments (for example in the SEM) not only for a scintillation electron detector, but also as a significant imaging and analyzing SEM mode. So, the topic of CL is an important method for understanding of transition effects and of other processes not only in scintillators, but also in many other solids studied. In our laboratory, CL has been studied using the modular CL equipment, where a transparent specimen (including a transparent substrate if necessary) is positioned at the face of the light guide. The CL emission is guided from the substrate side to aphotocathode of the photomultiplier tube (PMT). At the CL spectra measurement, the emitted light is guided to the spectrometer where the PMT is positioned at the output slit. |
