Abstract
AbstractCubic GaN nanoparticles and nanorods have been successfully synthesized from the nitridation of nanocrystalline GaP at 500 °C for 30 min, by manipulating different heating rates in nitrogen. The results of the thermal stability studies of nanocrystalline GaP under N2 at different heating rates support the idea that cubic GaN can form from GaP via a N−P metathesis mechanism. The morphology of the cubic GaN can be controlled by variation of the external synthetic parameters such as the rate of heating. This work shows that it is very simple to synthesize cubic GaN nanoparticles or nanorods and opens a wide route towards detailed studies of the fundamental properties and potential applications of semiconductor nanocrystals.
