Energy transfer processes are very important in solid-state laser systems because they can cause an enhancement of the luminescence emission resulting in a reduction of the laser threshold. In this work, a detailed investigation to understand the bas

The energy transfer from the 6P7/2 level of Gd3+ to the 2P3/2 level of Er3+ is studied in the phosphor Y0.34Gd0.65Er0.01F3. The lifetime of the 6P7/2 level of Gd3+ decreases substantially in the presence of Er, indicating that the transfer is nonradi
