摘要
本文系统研究了在有机溶剂中常压合成GaP纳米晶过程中反应温度、反应时间、反应体系的均匀性和原料的比例等关键影响因素。GaP纳米晶的产率、形貌以及平均粒度随着这些关键因素的改变有很大的不同。制备的GaP纳米晶用X射线衍射仪和透射电镜进行了表征。发现了最优化的合成工艺条件 ,实现了GaP纳米晶的高产率(达 85 % )制备 ,而且形貌和粒度可以根据需要进行调控。
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.
