摘要
The novel simple method of GaN nanocrystallites synthesis is presented. Their structure and morphology was investigated. The average sizes of GaN nanocrystallites as determined from XRD and TEM measurements were ca.10nm. The Raman and photoluminescence spectra were measured and analyzed. It was found that the photoluminescence of GaN nanocrystallites exhibits the broad band with a maximum in the red at 650nm. This luminescence was strongly quenched with increasing temperature.
