Photon Cascade Emission through Energy Transfer in Pr3+ and Er3+ Codoped System

Keywords： rare earths

Energy transfer processes in Pr3+ and Er3+-codoped CaAl12O 19 crystal from 12 to 290 K were studied. Energy transfer from Pr3+ t o Er3+ ions in this system was observed. The transfer can partially conve rt the 1 S0 UV fluorescence of Pr3+ into green emission of the characteristic of Er3+. The efficiency of the energy transfer was estimat ed based of the spectroscopic data. The temperature dependence on the transfer was also discussed.
