Abstract

Knowledge on the excitation energy transfer in the phosphor materials is necessary to improve their luminescence characteristics. Using theoretical methods we investigated the excitation energy transfer in Eu-doped BaMgAl ₁₀O₁₇ and NaAl₁₁O₁₇. We developed a new calculation method for excitation energy transfer through exchange interaction. The results show that the excitation energy is transferred through the conduction plane in BaMgAl₁₀O₁₇ and the spinel block in NaAl₁₁O₁₇. Structural defects forming localized levels seem to decrease the efficiency of the energy transfer.
