摘要
本文利用辐射法合成了纳米Ag-PVA-H2O溶胶,AFM和TEM表征结果显示,纳米银粒子的粒径分别为24nm和22.6nm,结果基本一致。溶胶的紫外可见光吸收光谱显示,与文献报道的纳米银特征吸收峰(403.5nm)相比,红移了33.5nm,吸收发生了明显的展宽现象。本文对结果进行了分析和讨论。
In this paper, the synthesis of nano-Ag-PVA-H2O sol was described. The nanosilver particles were observed by AFM and TEM. The average diameter of the nanosilver particles was about 24nm （AFM） and 22.6nm （TEM） respectively. The optical absorption property of nano Ag-PVA-H2O sol was researched. Comparing with the value reported by literature, the absorption peak of 403.5 nm presents a 33.5nm red-shift and the absorption line is broadened. The results were analyzed and discussed.
