摘要：

The Raman and Mossbauer spectra of nano-SnO2 specimens with crystallite size 3-16 nm were measured at room temperature. Specimens were annealed at different temperatures in oxygen atmosphere and vacuum respectively. Both the Raman and Mossbauer spectra of the specimens consist of crystalline and interface (or surface) components. The effects of oxygen deficiency on the Raman spectra are presented and correlated with the changes of the Sn-O bond properties, which were obtained from the corresponding Mossbauer spectra.
