Abstract : The objective of this research program was to synthesize luminescent oxide or halide nanoparticles with improved brightness and scintillation efficiency under excitation by energetic X-ray and gamma radiation. Improved brightness and efficiency was achieved by growth of undoped and doped nanoparticles with a core/shell nanostructure. The nanoparticle properties characterized included photoluminescence-PL, crystallography, particle size distribution, quantum efficiency and nuclear spectroscopic responses.
