摘 要：Through a hydrothermal route,the Er3+and Tm3+co-doped SrYbF5nanosheets were synthesized.The resulting samples were characterized by X-ray diffraction,scanning electron microscopy,energy dispersive X-ray spectroscopy and luminescence spectra.Under the excitation of 980 nm laser irradiation,the upconversion emissions of Tm3+ions centered at 474 nm（1G4→3H6）,679 nm（3F2→3H6）,699 nm（3F3→3H6）,803 nm（3H4→3H6）and emissions of Er3+ions centered at 522 nm（2H11/2→4I15/2）,543 nm（4S3/2→4I15/2）,654 nm（4F9/2→4I15/2）were observed.The upconversion emissions of Er3+ions were adjusted by the concentration of Tm3+ions.The energy transfer mechanisms among Er3+-Yb3+-Tm3+in SrYbF5nanosheets were discussed.
