摘要
以葡聚糖为还原剂和稳定剂,采用微波高压液相绿色合成法制备了黄色银纳米粒子。用吸收光谱和共振散射光谱研究其制备条件的影响。在413 nm处产生最大吸收峰,在486 nm处产生一个最强共振散射峰。实验表明:该法制备的银纳米粒子粒径均匀,平均粒径为16 nm,其稳定性和分散性好,合成方法简便、快捷。
The silver nanoparticles in yellow color were prepared by microwave high-pressure synthetical method, using dextran as reducing agent and stabilizer The maximum absorption peak of silver colloidal was at 413 nm, and its strongest resonance scattering peak was at 486 nm. The influence of main conditions on the microwave reaction was studied with absorption spectrometry and resonance scattering spectroscopy. The experimental the result showed that the silver nanoparticles had wcll-distributity and good stability. The average diameter of silver nanoparticles was 16 nm. The procedure was rapid and convenient.
