The diploma thesis deals with the combined use of SEM and SPM techniques using optical fiber, which is used to collect the cathodoluminescent signal in close proximity to the sample. The thesis also includes a research section, which lists description of CPEM technique, the techniques used to modify the optical fiber, theoretical introduction to cathodoluminescence and techniques used to measure it. The practical part discusses the obtained measurement results and the problems that occurred in the process of modification of the optical fiber, its use as an SPM probe and in the measurement of cathodoluminescence active materials. |
