In this paper,Tb3+,Yb3+ Co-doped CeF3 nanophosphors were synthesized using the microwave-assisted heating hydrothermal treatment(M-H).The XRD and SEM images indicate that the samples were cubic phase with nanoscale.Excitation and emission spectra at room temperature are shown that the sample can absorb the ultraviolet light around a broad band from 250 nm t0 400 nm,then emits light at 300 nm which corresponds to the transitions from 5D t0 4F of Ce3+,480 nm,540 nm,583 nm,620 nm which correspond to the transitions from 5D4 t0 7F6、5、4、3 of Tb3+,973 nm which corresponds to the transitions from 2F5/2-2 F7/2 of Yb3+.In the emission spectra,it is clear that emission intensity of Ce3+ decreases and Tb3+ decreases with increasing Yb3+,this can improve that energy transfer from Ce3+ to Tb3+ to Yb3+ may occur.In near infrared emission area,it is worthy to note that a distinct emission centered at 973 nm owing to transitions among different Stark levels of 2FJ(J = 5/2,7/2)of Yb3+ ions was observed under 250 nm excitation.This also can prove the energy transfer from Ce3+ to Tb3+ to Yb3+.The occurrence of energy transfers from in Tb3+,Yb3+ Co-doped CeF3 nanophosphors,which lead to the intensity NIR emission at 900-1050 nm matching to energy of Si band gap of Si-based solar cells.Therefore,the kinds of materials are promising for application in modifying solar spectral and enhancing conversion efficiency of Si-based solar cells.
