Abstract

Highly luminescent beryllium nitride powder (Be₃N₂) has been synthesized by direct nitridation of metallic beryllium with ultra-high purity ammonia (NH₃) in a horizontal quartz tube reactor at 1100 °C. The calculated Gibbs free energy for this reaction at 1100°C is -602.20 kJ/mol and the equilibrium constant is 2.7×10²², this make workable the process at the conditions chosen for this synthesis. The Be₃N₂ produced by this method is a light-gray powder which showed the typical high hardness of this material. The Be₃N ₂ powders synthesized in this research consist mostly of agglomerates formed of regular cubic polyhedrons between one and two microns long each as shown by electron microscopy. These crystallites have a cubic structure as shown by X-ray diffraction and exhibit high intensity room temperature cathodoluminescence with a peak around 356 nm (3.48 eV), which is related to their near-band-edge emission. These properties make this material a strong candidate for wide-band optoelectronic applications such as ultraviolet-lasers, sensors and light-emitting diodes.
