Abstract

The syntheses of cubic gallium nitride (c-GaN), and cubic boron nitride (c-BN) nanopowders, including erbium (Er) doping, are investigated. The powders are produced using a novel, aerodynamically-enhanced plasma process, along with in-situ laser-based diagnosis of the gas-phase flow field and as-synthesized nanoparticles. The nanopowders are characterized for phase and crystallinity, morphology and primary particle size, aggregate particle size, powder surface area, particle size distribution, and precursor conversion. Rare earth (RE) is doped directly during the plasma synthesis process, and the untreated nanopowders are characterized spectroscopically. Photoluminescence of the powders and absorption/emission characteristics and emission life times of pellets produced from them are measured.
