Abstract:
1. A nanophosphor composite scintillator composition comprising: a solid matrix; the solid matrix including at least one surface modified nanophosphor scintillator particle selected from the group consisting of yttrium oxide, yttrium tantalite, barium fluoride, cesium fluoride, bismuth germatate, zinc gallate, calcium magnesium pyrosilicate, calcium molybdate, calcium chlorovanadate, barium titanium pyrophosphate, a metal tungstate, a cerium doped nanophosphor, a bismuth doped nanophosphor, a lead doped nanophosphor, a thallium doped sodium iodide, a doped cesium iodide, a rare earth doped pyrosilicate, and a lanthanide halide; wherein the nanophosphor scintilltor particle is surface modified by functionalizing the particles to provide a neutral surface to achieve particle dispersion in the solid matrix.
