The Raman spectra, infrared spectra and upconversion luminescence spectra were studied, and the effect mechanism of OH À groups on the upconversion luminescence of Er 3+ -doped oxyhalide tellurite glasses was analyzed. The results show that the phonon energy of lead chloride tellurite (PCT) glass wa
