摘要：

Perovskite CaTiO3: Yb3+, Er3+ nanocubes with tunable upconversion luminescence (UCL) were prepared by a solvothermal method. The structure and morphology of the final product after being sintered at 700 degrees C for 2 h were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The upconversion emissions of CaTiO3: Yb3+, Er3+ under the excitation of 980 nm diodes laser consist of two typical emission bands from F-4(9/2) -> I-4(15/2) and S-4(3/2), H-2(11/2) -> I-4(15/2) transitions. The UCL properties depending on the doping contents of Yb3+ to Er3+ were investigated in detail. The maximum R/G ratio was observed at Yb3+ concentration of 15 mol%. The multiphotonic upconversion mechanism of controllable red-to-green ratio in CaTiO3: Yb3+, Er3+ nanocubes was addressed based on both steady state and transient spectroscopy data.
