Abstract
Photoluminescence characteristics and the energy transfer between Ce3+ and Eu2+ in CaAl12O19 host lattice have been investigated. A series of concentrations of Ce3+ ion with a fixed Eu2+ concentration in doubly doped CaAl12O19 : Ce3+Eu2+ have been studied. The indirect energy transfer has been observed between Ce3+ and Eu2+ through the Ce3+-UMe complex in CaAl12O19 host lattice. The two nonradiative relaxation processes from the excited levels of Ce3+-OMe complex; one, to the lower emitting level of Ce3+-OMe complex themselves and the other, to the Eu2+ site are competing processes.
