摘要	The step energy transfers from Pr3+ 4f5d state to Ce3+ 5d state followed by energy back transfer from Ce3+ 5d state to Pr3+ D-1(2) level are studied. The Ce3+ -> Pr3+ energy back transfer upon Pe(3+) 4f5d excitation is found to be more efficient than the normal Ce3+ -> Pi(3+) energy transfer upon Ce3+ 5d excitation. The efficient energy back transfer is attributed to preferential excitation of the Ce3+ ion with an adjacent Pr3+ surrounding in Pr3+ -> Ce3+ energy transfer of the first step, whereas Ce3+ is excited randomly in the normal energy transfer. The efficiencies of Ce3+ -> Pe(3+) energy back transfer as a function of Ce3+ and Pr3+ concentration are evaluated, respectively. (C) 2017 Elsevier B.V. All rights reserved.
