A laboratory experiment is described in which students synthesize silver nanospheres and transform them into other anisotropic morphologies (decahedral and disks) through a photochemical process. The photochemical transformation was followed by visible spectroscopy, and the resulting morphologies were analyzed using scanning electron microscopy. This experiment, which may be included in a nanotechnology or materials chemistry laboratory course, introduces students to nanotechnology and shows how anisotropic nanoparticle synthesis methods are not limited to chemical reduction or seed regrowth.

演示银纳米粒子的光化学转化

描述了一个实验室实验，学生可以通过光化学过程合成银纳米球，并将其转变为其他各向异性形态（十面体和盘状）。光化学转变之后是可见光谱，并且使用扫描电子显微镜分析所得的形态。该实验可能包括在纳米技术或材料化学实验室课程中，它向学生介绍了纳米技术，并显示了各向异性的纳米颗粒合成方法如何不仅限于化学还原或种子再生。
