Upconversion fluorescence modulation of CaTiO3∶ Yb3+/Er3+nanocubes via Zn2+introduction
文献摘要：
To investigate the effect of Zn2+ions on the luminescence properties of rare earth(RE)doped calcium titanate mate-rials,CaTiO3∶Yb3+/Er3+/Zn2+nanocubes with uniform size were prepared by solvothermal method in this paper.They were respectively characterized by X-ray diffractometer(XRD),scanning electron microscope(SEM),photolumines-cence(PL)spectroscopy and their fluorescence lifetimes.The results show that the average size of the nanocubes is about 550 nm×650 nm×850 nm with good upconversion luminescence(UCL)properties.Under 980 nm laser excita-tion,the effects of the ratio between activator Er3+and sensitizer Yb3+and Zn2+doping on the upconversion fluores-cence properties were investigated,and the optimal ion ratio was obtained.The results of steady-state spectra show that the strongest fluorescence intensity of CaTiO3∶Yb3+/Er3+was obtained with the addition of 10 mol％Zn2+at a Yb3+/Er3+molar doping ratio of 3∶0.3,which was attributed to the crystal field asymmetry generated by the introduc-tion of Zn2+ions.The energy transfer and upconversion mechanism between Yb3+and Er3+ions in CaTiO3 nanocubes were investigated by analyzing the upconversion fluorescence kinetics.
