摘要
在聚乙烯醇(PVA)、聚乙烯吡咯烷酮(PVP)和壳聚糖(CTS)等软模板存在下,通过液相化学还原法制备出各种形貌的银纳米粒子。重点讨论了PVP软模板及其浓度、温度、超声等因素对银纳米粒子形貌的影响,运用TEM、XRD、IR、UV-Vis等测试技术对样品进行了表征,探讨了银纳米粒子的形成机理,并对银纳米粒子的光学性质进行了研究。
In the presence of soft-template such as PVP, PVA and CTS, Ag nanoparticles with different morphologies were prepared through liquid phase chemical deoxidization method. The effect factors, such as surfactants, temperature and ultrasonic action were discussed. The products were characterized with transmission electron microscopy（TEM）, ultra-violet-visible（UV-Vis）, infrared absorption spectroscopy（IR） and X-ray diffraction（XRD）. The growth mechanism and the photoelectric properties ofAg nanoparticles were studied.
