| Abstract: | The key factors in preparation of GaP nanocrystals in organic solvent were studied,including reaction temperature,reaction time,uniformity of reaction system,mol ratio of reactants.It is found that the yield,microstructure and particle size of the prepared GaP nanocrystals are very different with the change of these key factors.The prepared GaP nanocrystals were characterized by X-ray diffractometer and transmission electron microscope.The optimized synthesis conditions of GaP nanocrystals were obtained.The GaP nanocrystals can be prepared at high yield of 85% and the microstructure and particle size can be controlled. |
