| 摘 要： | 以乙酸锌、硝酸镉和硫化钠为原料，室温下，采用微乳液法合成ZnS、CdS纳米粒子。利用rIEM、XRD、Raman、UV-Vis和PL等检测手段对产物进行表征。结果表明，合成的zns纳米晶粒径在25m左右，为立方β-Zns晶相；ω值对合成纳米cds的形貌和粒径产生重要影响，纳米Cds粒径为5nm左右，在紫外吸收光谱和荧光发射光谱上均表现出明显的特征，可作为荧光量子点使用。

| Abstract: | Applied zinc acetate, cadmium nitrate and sodium sulfide as raw material, ZnS and CdS nanoparticles was synthesized by microemulsion method at room temperature. The product was characterized by TEM, XRD, Raman,UV-Vis and PL. The results showed that the particle size of synthetic ZnS nanocrystalline was about 25nm, as cubic β -ZnS phase; the value of ω had an important effect on the synthetic nano-CdS morphology and particle size. The particle size ofCdS nanometer was about 5nm and the nanoparticle showed obvious features in the UV absorption spectra and fluorescence emission spectra, could be used as fluorescent quantum dot. |
