Abstract
Abstract We investigate thermal effects upon infrared to visible frequency upconversion fluorescence emission in Er3+-doped chalcogenide glasses, pumped under anti-Stokes, Stokes and resonant excitation. The upconversion emission signals is found to decrease with increasing temperature in the range of 23–200 °C. The observed thermal effect is modeled by conventional rate equations considering a temperature-dependent effective absorption cross-section for the 4 I 15/2 → 4 I 9/2 and 4 I 11/2 → 4 F 3/2 , 4F5/2 erbium transitions. The temperature dependence is mainly attributed the nonradiative decays. This model accurately reproduces the experimental results.
