Abstract
Energy transfer processes in Pr3+ and Er3+ -codoped CaAl12O19 crystal from 12 to 290 K were studied. Energy transfer from Pr3+ to Er3+ ions in this system was observed. The transfer can partially convert the 1S0 UV fluorescence of Pr3+ into green emission of the characteristic of Er3+. The efficiency of the energy transfer was estimated based of the spectroscopic data. The temperature dependence on the transfer was also discussed.
