| 摘 要： | 硝酸银水溶液缓慢注入较高温(>100°C)的PVP乙二醇溶液中,还原得到不同颜色的纳米银溶胶。实验表明,纳米银溶胶的外观颜色和反应温度与PVP浓度有关;紫外-可见光谱分析表明,该法合成的纳米银溶胶的特征吸收峰在400~500 nm之间,吸收峰位移主要是由纳米银颗粒形貌不同引起的;透射电镜分析表明,纳米银颗粒的形貌是无规则的。

| Abstract: | Nano-silver colloids with different colors were synthesized by injecting silver nitrate solution into the glycol solution of PVP at high temperature(>100 °C).The color of nano-silver colloids was infuenced by the reacting temperature and the concentration of PVP. Feature absorptions of the colloids obtained from UV-Vis analysis appeared at 400~500 nm,and the shift of feature absorption peaks resulted from different morphology of nano-silver.TEM analysis confirmed that the morphology of the nano-silver was irregular. |
