Abstract:ZnO nanopowders were prepared by the sol-gel techniques with two kinds of solvent. Microstructure of the powder samples was examined by XRD and TEM. The results indicate that two ZnO samples have the same crystal and energy band structure. Their photoluminescence (PL) spectra in the ultraviolet region are analogous, but their photoluminescence (PL) spectra in the visible region are different. The reason is that two kinds of solvent with different polarity result in the difference in configuration and distribution of the sample surface states in the two systems.
