Strategy for Enhanced Light Output from Luminescent Nanoparticles

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.
