Novel Synthesis of Nanocrystalline Gallium Nitride Powder from Gallium(III)-Urea Complex

摘要

A novel method is reported for the preparation of wurtzite gallium nitride (GaN) powder with a controlled particle size from nanometer ot micron scale,using gallium(III)-urea complex as the precursor.The GaN powders as synthesized at various temperatures showed strong and distinct photoluminescence characteristics.The method developed here may provide a simple,potentially economical way to form other nitride materials with desired performances.
