Room temperature photoluminescence spectra of the as-synthesized samples display a strong yellow emission at about 600nm and a weak blue emission at about 430nm. The as-prepared and annealed Sn1−x NixO2 (x=0, 0.01, 0.02, 0.04) were characterized by X-ray diffraction, field emission scanning electron microscopy, Raman spectrum, UV-Vis absorption spectra, and room temperature photoluminescence spectra. By investigating the relationship between the Raman band centered at 560cm−1 and the photoluminescence of the samples, we suggest that the broad yellow emission and weak blue emission primarily originate from singly ionized oxygen vacancies and tin interstitials, respectively.
