| 摘 要： | 通过溶胶-凝胶法制备了5~31 nm氧化锌纳米晶,测量了它们的拉曼光谱,结果表明二级拉曼模随粒径减小相对强度增大,归因于尺寸效应.新出现的938 cm-1模指认为来自表面氧空位. |
| 关 键 词： | ZnO纳米晶 拉曼光谱 尺寸效应 |

| Abstract: | Through the method of Sol-Gel,we prepared the ZnO nanocrystals in size of 5-31 nm,and then their Raman spectra were measured.Results showed that the intensity of two-order Raman scattering was increased while the grain size decreased,due to size effect.New 938 cm-1 mode was assigned to oxide vacancies on surface of nanocrystal. |
| Keywords: | ZnO nanocrystal Raman spectrum size effect |
