Abstract

ZnO nanoparticles have a strong photoluminescence but weak scintillation luminescence which is an issue for their applications in radiation detection and dosimetry. To enhance their luminescence, ZnO nanoparticles were made into nanocomposites with CeF₃ nanoparticles. As a result of energy transfer from CeF₃ nanoparticles in the composites, the photoluminescence of ZnO nanoparticles is enhanced 30 times and their X-ray luminescence is enhanced 4 times. The combination of CeF₃ and ZnO nanoparticles makes CeF₃/ZnO nanocomposites promising scintillators for radiation detection.
