The nano ZnO and nano composite ZnO/SnO2 materials were prepared by sol-gel method, then the prepared specimens were treated by high pressure method of which the pressure is up to 6 GPa. X-ray diffraction (XRD) and transmission electron microscopy (TEM) and photoluminescence spectrometer were employed to study structures and luminescence properties of the specimens. The results indicate that the particle sizes of ZnO and ZnO/SnO2 decrease 5.9% and 26.3% respectively after high pressure treatment. And the photoluminescence spectra show that photoluminescence spectra intensity of nano ZnO and composite ZnO/SnO2 materials both reduce after high pressure treatment, but the reduced intensity of composite ZnO/SnO2 materials is less than the one of pure ZnO, and the possible reasons are discussed.
