Amorphous GaN nanoparticles were synthesized by the {ital in situ} thermal decomposition of cyclotrigallazane incorporated into a polystyrene{endash}poly({ital N,N}-dimethyl-4-vinylaniline) copolymer. Transmission electron microscopy, energy dispersive x-ray spectrometry, and x-ray photoelectron spectroscopy show that the composite material consists of amorphous GaN nanoparticles (average diameter {approximately}40 nm) well dispersed in the copolymer. The photoluminescence spectra show blue light emission from the amorphous GaN nanoparticles, peaked at {approximately}426 nm. {copyright} {ital 1999 American Institute of Physics.}
