Abstract
Optical properties of fluorophosphate Er3+-Yb3+ fiber preforms with different concentrations of ErF3 and YbF3 are investigated in the temperature interval 25-300 °C. The temperature-dependent absorption spectra and luminescence at 1535 nm (under the λ = 970 nm excitation) spectra as well as the 4I13/2 â 4I15/2 luminescence decay times are used to compute the luminescence cross-section Ïe(λ). Our results show that in the range of the temperature investigated the quenching effect due to the temperature increase weakly affects the luminescence cross-section and decay time, which make these materials promising for fiber-optics applications.
