| Abstract: | Energy transfer processes in Pr 3+ and Er 3+-codoped CaAl 12O 19 crystal from 12 to 290 K were studied. Energy transfer from Pr 3+ to Er 3+ ions in this system was observed. The transfer can partially convert the 1S 0 UV fluorescence of Pr 3+ into green emission of the characteristic of Er 3+. The efficiency of the energy transfer was estimated based of the spectroscopic data. The temperature dependence on the transfer was also discussed. |
