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.

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.
