A report on the optical spectroscopy of bulk gallium nitride crystals from Na-Ga melt was presented. The high purity was attributed to the low growth temperature and pressure. Low temperature excitonic photoluminescence (PL) and reflectance spectra was shown. The residual zinc implied that intentional zinc doping was possible and was used to make high resistivity material for microwave applications.
