| 摘 要： | 0引言CdS是一种重要的Ⅱ-Ⅵ族半导体,其独特的光电化学性能引起人们的广泛关注,而其性能与晶粒尺寸、晶体结构等密切相关,因而CdS的纳米结构的研究备受关注1￣3]。目前,制备CdS纳米粒子的主要方法有溶剂热法4],化学浴沉积法5],微乳液法6]等。微乳液是合成球形纳米粒子的良好介质,具有实验装置简单,操作方便,应用领域广并且有可控制微粒的粒度等优点7]。但其在室温条件下合成的CdS粒子的结晶性较差,严重影响其光电性能。Gan和Liu等8]曾在NP5-NP9/PE/SOL微乳液中,在室温及水热条件下合成ZnS:Mn发光纳米材料,来提高在微乳液中制…

| Abstract: | The CdS nanoparticles with good crystallinity were prepared by hydrothermal method in microemulsion composed of poly oxyethylene lauryl ether/water/ cyclohexane/butanol. The structure and the size of the nanoparticles were analyzed by TEM and XRD. The UV-Vis optical absorption of the samples was also investigated.The results show that hydrothermal treatment is an effective method to prepare CdS nanoparticles of hexagonal structure at low temperature. The particles were in dimensional uniformity. The diameter of the nanoparticles decreased with the increase of the molar ratio of water to surfactant. The minimum diameter of the nanoparticles prepared in this work was 10 nm. Obvious blue-shift were observed in the UV-Vis absorption. |
