摘 要：By controlling the concentration of Tb3+,a series of GdF3 samples were synthesized by a hydrothermal method without any surfactant.The samples were characterized by X-ray diffraction（XRD）patterns,field emission scanning electron microscopy（FE-SEM）images,photoluminescence（PL）excitation and emission spectra as well as luminescent dynamic decay curves.The optical properties of Tb3+,the concentration quenching phenomenon of Tb3+,and the energy transfer from host Gd3+to Tb3+were investigated and discussed based on the concentration of Tb3+in the GdF3 samples.The experimental results suggested that the optical properties of Tb3+and the energy transfer from host Gd3+to Tb3+could be adjusted by the concentration of Tb3+in the samples.
