Abstract
Fluoroindate glasses co-dopped with Er3+ at different concentrations were synthesized using the melting quenching technique, where it was observed that the emission peak located at 1.53 μm associated with 4I13/2→4I15/2 transition of Er3+ increases up to 11.5 times with increasing ErF3 content up to 1.4 mol. %. Such increase is significant due to their proximity with one of the most important telecommunication windows (1.55 μm) which the spite of all the studies around it, some challenges like its efficiency need to be optimized. The effect of sensitization of the Er3+ by Yb3+ ions was also evaluated. The increase in luminescence intensity (~19%) was obtained by co-doping of 1.4ErF3 glass by 0.8YbF3. This effect is related to the efficient Yb3+→ Er3+ energy transfer.
