CeO₂ (ceria) is one of the remarkable materials as a surrogate for a nuclear fuel and transmutation target. We have investigated the production and charge state of point defects and F-centers in ceria by using in-situ cathodoluminescence (CL) spectroscopy under high-energy electron irradiation in a high voltage electron microscope (HVEM).
