Preparation, Stability, and Luminescence of Gallium Nitride

Abstract

Gallium nitride has been prepared from gallium oxide and ammonia at temperatures from 600° to 1100°C. The emission of various preparations under cathode ray excitation has been investigated. Dissociation studies indicate the thermal instability of at temperatures as low as 600°C. Observed emission spectra are discussed in terms of preparation temperature and dissociation.
