Abstract
Heterogeneous reactions between MBr(3) (M = Ga, In) and Li3N in reflux ing aromatic or aromatic/diglyme solvents were investigated as a poten tial route to nanocrystalline GaN and InN powders. For M = Ga, the pyr olysis of the as-prepared precursors at 450-500 degrees C under vacuum or NH3 yielded nanosized GaN and elemental Ga. Gallium nitride was ch aracterized by XRD, XPS and UV/vis spectroscopies, TEM microscopy, and elemental analysis. For M = In, the reactions were highly solvent dep endent and resulted exclusively in redox products such as indium(I) br omide, InBr, and elemental In.
