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⁺-U_Me complex in CaAl₁₂O₁₉ host lattice. The two nonradiative relaxation processes from the excited levels of Ce³⁺-O_Me complex; one, to the lower emitting level of Ce³⁺-O_Me complex themselves and the other, to the Eu²⁺ site are competing processes.
