摘　　要：CdSe纳米晶是Ⅱ-Ⅵ族半导体中研究最多的材料之一。由于其发射波长随纳米晶的尺寸而改变,从而可以覆盖从绿到红的宽光谱范围,因此CdSe纳米晶可以应用于生物标记和荧光显示等领域,各种制备CdSe纳米晶的方法也应运而生。因制备方法的不同,所得CdSe纳米晶的粒径、相结构及形貌也不同,进而影响CdSe纳米晶的性质。本文归纳了7种典型的制备特殊形貌CdSe纳米晶的最新方法,并对各种方法的优缺点做了简单评价。最后,对这一领域未来的研究和发展方向做了展望。As an important Ⅱ-Ⅵ group semiconductor material,CdSe nanocrystals have drawn much attention recently due to its unique size-dependent fluorescence tunable across the visible spectrum. CdSe semiconductor nanocrystals exhibit great potential for using as a new type of fluorescence materials and labeling materials for biological research. Various preparation methods have been developed to synthesize different size and morphology CdSe nanocrystals. With the different preparing methods,the diameter,phase structure,morphology uniformity,and properties are also different accordingly. In this paper,the seven typical methods of preparation and control of morphology of CdSe nanocrystals are summarized in detail. Meanwhile, their corresponding strongpoints and weaknesses are also reviewed. The challenges about preparing CdSe nanocrystals are figured out and the future research directions are also proposed.
