摘要: We present an investigation of dynamical processes nonradiative energy transfer (ET) between Ce3+ and Pr3+, Pr3+ ions in Y3Al5O12:Ce3+, phosphor. Photoluminescence spectroscopy fluorescence decay patterns are studied as a function concentrations. The analysis based on Inokuti–Hirayama model indicates that the ET from lowest 5d state to D12 quenching through cross relaxation involving ground both governed by electric dipole–dipole interaction. An increase Ce3+–Pr3+ rate followed enhanced red emission line relative yellow band only increasing concentration is observed. This behavior attributed spectral overlap integrals excitation due fact shifts side with while dose not move. For C...
