摘要：
CaTiO3:Dy3+/Eu3+ phosphors were synthesized by a solid state reaction. The XRD and FTIR results demonstrate the single phase of the CaTiO3:Dy3+/Eu3+ phosphors. The overlap between the emission spectrum of Dy3+ and the excitation spectrum of Eu3+ suggests possible energy transfer from Dy3+ to Eu3+. And the energy transfer was confirmed by the decreasing Dy3+ emission intensity and lifetime with the increasing Eu3+ concentration. The comparable emission intensities of blue, yellow and red emissions for CaTiO3:Dy3+/Eu3+ phosphors mean that a possibility for the generation of white light by designing the concentrations of Dy3+ and Eu3+.
