Abstract

We report the synthesis of a nanocomposite materials consisting of gallium nitride (GaN) confined in the well ordered mesoporous transparent matrix MCM-41 with the help of the metalorganic single source precursor triazido(trimethylamine)gallium using solution impregnation technique. The loading of the pores of MCM-41 with GaN was confirmed by chemical analysis, XRD, TEM, BET, NMR and optical spectroscopy (PL and PL-excitation spectroscopy). The composites exhibit a blue shift of the bandgap of GaN due to quantum confinement.

The spectra are not corrected for the spectral sensitivity of the equipment. The spectral components were weighted by he spectral slitwidth.Google Scholar
