在本文中，我们总结了我们的结果，改变半导体和金属纳米晶体的尺寸和形状的影响。的尺寸（从3.5到1.1 nm）和形状（从球形到棒）的CdSe纳米晶体的变化被发现影响它们的光学和非辐射性能。在金准球形纳米晶体，结果的周围介质的电子-声子弛豫的依赖。对于金纳米棒，其自组装机制的结果和结论。研究了它们表面的增强拉曼散射，并与球形颗粒表面的拉曼散射进行了比较。
In this paper, we summarize our results on the effect of changing size and shape of semiconductor and metallic nanocrystals. The change in size (from 3.5 to 1.1 nm) and shape (from spherical to rod) of CdSe nanocrystals is found to affect both their optical and nonradiative properties. In gold quasi-spherical nanocrystals, results on the dependence of the electron-phonon relaxation of the surrounding medium are presented. For gold nanorods, results and conclusions on the mechanism of their self-assembly are presented. Enhanced Raman scattering on their surfaces is studied and compared with that on spherical particle surfaces.
