Nanocrystalline Cubic Yttria: Synthesis and Optical Properties

Abstract

For the first time Y2O3 has been deposited in the cubic equilibrium structure with a small particle size of 10 nm in a single processing step; the Figure shows the XRD patterns with Bragg peaks consistent with the structure. This communication shows that this good crystalline quality makes Y2O3 a promising host material for doped nanocrystalline phosphorus with high efficiency in lighting systems.
