The Raman spectra, infrared spectra and upconversion luminescence spectra were studied, and the effect mechanism of OH{sup -} groups on the upconversion luminescence of Er{sup 3+}-doped oxyhalide tellurite glasses was analyzed. The results show that the phonon energy of lead chloride tellurite (PCT) glass was lower than that of lead fluoride tellurite (PFT) glass, but upconversion luminescence intensity of Er{sup 3+}-doped PFT glass was higher than that of Er{sup 3+}-doped PCT glass. The analysis considers that it was attributed mainly to the effect of OH{sup -} groups. The lower the absorption coefficient of the OH{sup -} groups, the higher the fluorescence lifetime of Er{sup 3+}, and as a result the higher upconversion luminescence intensity of Er{sup 3+}. In this work, the effect of OH{sup -} groups on the upconversion luminescence of Er{sup 3+} was bigger than that of the phonon energy.
