摘要：
infrared-to-visible up-conversion luminescence (UCL) of RE3+ singly-doped and RE3+/Yb3+ co-doped CaIn2O4 (RE-Tm, Pr and Ncl) phosphors were investigated under 980 nm excitation. The energy transfer from Yb3+ to RE3+ plays an important role in the UC process and the introduction of Yb3+ significantly enhances the UCL intensities of CaIn2O4: RE3+. The energy level diagrams and the possible UCL mechanisms of CaIn2O4: RE3+, Yb3+ (RE =Tm, Pr and Nd) were proposed based on the results of power dependence of the UCL intensities.
