| Research Abstract |
In this study, I tried to establish a method for analyzing compounds containing rare earth elements utilizing cathodoluminescence phenomenon (CL) in which visible light is emitted as the result of electronic transitions between the conduction and valence bands by the bombardment of electrons. After that, I tried to establish a method for analyzing an grain-boundary (micro-region) of yttrium doped nbarium zirconate (BZY) utilizing CL phenomenon. The CL analysis can detect rare-earth elements of ppm order in compounds. Also, the CL analysis can separate rare earth elements in compounds containing seraral rare earth elements. However, the CL analysis was not able to analyze micro-region of BZY becasue the electron beam was broadened due to the high energy of the electron beam (15 keV).
