Abstract

Eu³⁺, Li⁺-codoped ZnO:Zn phosphor with intense Eu³⁺ emissions upon indirect excitation of near-UV light has been synthesized under reducing condition. Steady-state and time-resolved photoluminescence and diffuse reflectance spectra are measured to investigate properties of the luminescence. The results suggest that there exists prominent energy transfer from ZnO host to Eu³⁺ ions. A series of energy levels as temporary storage of excitation energy play a crucial role on this energy transfer process. Two kinds of Eu sites in Eu³⁺, Li ⁺-codoped ZnO:Zn are distinguished based on the emission and excitation spectra in comparison with pure Eu₂O₃.
