Abstract
Efficient infrared-to-visible conversion by Er3+/Yb3+-codoped PbTiO3 perovskite will be reported. The process is observed under 980Â nm laser diode (GaAs:Si) excitation and results in the generation of green (â¼555Â nm) and red (â¼655Â nm) emission. The main mechanism that allows for up-conversion is attributed the energy transfer among Yb and Er ions in excited states. The power up-conversion efficiency for red emission is predominant in this material. The results illustrate the large potential of this new class of material for photonic applications involving optoelectronics devices.
