以硫代乙酰胺(TAA)为前驱体,采用离子交换沉淀法在全氟磺酸离子交换膜(Nafion)中组装得到纳米ZnS晶体,利用高分辨电子显微镜(HRTEM)研究了ZnS纳米晶粒在膜中的形貌、大小和分布,采用紫外可见吸收光谱和荧光光谱分析了Nafion膜中组装ZnS晶体的光学性质.结果表明,在Nafion膜中合成的ZnS具有高的结晶度.进一步研究表明,不同体系下在Nafion膜中合成的ZnS纳米晶体表面缺陷含量不同导致了其光学性质的差异,其中,乙醇体系中合成样品缺陷含量丰富,荧光发射强度大. Nanosized ZnS crystals were assembled by Nafion ion exchange deposition method using thioacetamide (TAA) as precursor. The ZnS nanocrystals were characterized by high resolution electron microscopy (HRTEM) The optical properties of ZnS crystals assembled in Nafion membrane were analyzed by UV-vis absorption spectra and fluorescence spectra.The results show that the ZnS synthesized in Nafion membrane has high crystallinity.Further studies show that, The differences in the optical properties of ZnS nanocrystals synthesized in Nafion membranes under different systems led to the differences of their optical properties. Among them, the ethanol-containing samples had abundant defects and high fluorescence emission intensity.
