以硫酸镍（NiSO4.7H2O）作为镍源,以乙二醇和水作为混合溶剂,利用溶剂热法成功地制备了磷化镍（Ni12P5）微球。X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、透射电镜（TEM）和高分辨透射电镜（HRTEM）等分别对所制备样品进行了表征。结果表明,所得产物为纯的四方相磷化镍（Ni12P5）微球,粒径约为2～5μm;研究了不同实验参数对样品尺寸、形貌及微球形成过程等的影响。最后对磷化镍微球的发光性进行了研究。
In this paper,Ni12P5 microspheres were synthesized successfully via a solvothermal method,using nickel sulfate（NiSO4·7H2O） as Ni-sourece,ethylene glycol and water as solvent.The products were characterized by X-ray powder diffraction（XRD）,scanning electron microscopy（SEM）,transmission electron microscope（TEM） and high-resolution transmission electron microscope（HRTEM）,respectively.The results show that nickel phosphide（Ni12P5） were pure tetragonal phase and the particle diameters of microspheres was about 2-5μm.Then the effects of different experimental parameters on the products size,morphology and the formation of microspheres and the optical property were also investigated.
