Highlights: • We prepare Tm{sup 3+}-doped tellurite-zinc glasses with F{sup −} substitution. • Thermal stability becomes better with increasing F{sup −} in present glasses. • Tm{sup 3+} 1.8 μm radiative lifetime increases with F{sup −} concentration. • The origin of the increased lifetime has been discussed. - Abstract: The 1.8 μm emission properties of Tm{sup 3+}-doped zinc tellurite glasses modified by the substitution of ZnF{sub 2} are investigated in this paper. The thermal stability, Raman and phonon sideband spectra, transmission and absorption spectra, emission spectra and decay curves are discussed. It is found that substitution of fluoride ions into the zinc tellurite matrix produces dramatic increase in the emission lifetime of Tm{sup 3+} 1.8 μm emission. Absorption, Raman and phonon sideband spectra are used to estimate the local structure of Tm{sup 3+} ions. These analyses indicate structural change around Tm{sup 3+} ions caused by substitution of fluoride ions monitors the increased intrinsic radiative lifetimes. An increase in the measured radiative lifetimes of the Tm{sup 3+}:{sup 3}F{sub 4} → {sup 3}H{sub 6} transition is observed. The origin has been discussed and the reduction of OH{sup −} absorption, decrease of maximum phonon energy and phonon density are considered to be dominant in all of the nonradiative relaxations.
