YF 3:Ce 3+, YF 3:Tb 3+, and YF 3:Ce 3+/Tb 3+ nanocrystals were synthesized by an ethylenediaminetetraacetic acid (EDTA)-assisted hydrothermal method and characterized by X-ray diffraction and scanning electron microscope. In the excitation spectra, there is one broad excitation band at 285 nm for YF 3:Ce 3+ and 255 nm for YF 3:Tb 3+, which are related to the f-d excitations of the Ce 3+ and Tb 3+ in the host, respectively. In the emission spectra of YF 3:Ce 3+/Tb 3+ nanocrystals under different excitation wavelengths (285 and 255 nm), both spectra exhibit the emissions of Ce 3+ and Tb 3+, indicating that energy transfer could take place not only from Ce 3+ to Tb 3+ but also from Tb 3+ to Ce 3+ ions.
