Research on preparation and performance of Gallium nitride powder with preferred orientation

  • Received Date: 2017-03-01
  • The hexagonal wurtzite Gallium nitride(GaN) was prepared by calcining β gallium oxide(β-Ga2O3) in flowing ammonia. The XRD, SEM and TEM were employed to investigate the structure and morphology. The photoluminescence (PL) spectroscopy was used to collect photoluminescence spectroscopy of GaN perform the luminous property. The measurement results revealed that the obtained GaN had preferred orientation of (002), and the rod shape and grain size of GaN powders were similar to those of raw gallium oxide which were agglomerates of tens nanometers flake crystallites. The near-edge emission at 346 nm(3.584 eV) of Gallium nitride powders had a blue shift of 19 nm(187 meV) than that of bulk GaN material.
