摘要
利用直接溶液滴定法和以水玻璃体相制备硫化镉球形纳米粒子和针状粒子。通过扫描电镜、X射线衍射分析了所得样品的形貌和物相,结果表明所制备的硫化镉纳米粒子为球形和针状,其中,球形样品结晶程度低,部分样品被氧化,针状样品为纤锌矿型结构。
Two ways of synthesing cadmium sulfide nano-particles are reported. One way is that Cd(NO3 )2 solution is added in the dropwise way to the solution of Na2S, the other is that Cd(NO3)2 solution is added in the dropwise way to the rigorously-stired solution containing Na2S and water glass. The morphology and phase of cadimum sulfide nano-particles are delected by SEM and X-ray diffraction. The results show that the CdS nano-particles are spherical and spinulous respectively. The spherical particles are poor crystalline with somewhal of oxidation, and the spinulous particles are wurtzite structure.
