Abstract
CePO4:Tb3+ nanorods were successfully obtained via a simple hydrothermal method and combined with carbon dots (CDs) to obtain CDs@CePO4:Tb3+ nanorods. Due to the combination of CDs, the emission intensity of CDs@CePO4:Tb3+ nanorods increases about 92 times, compared with that of CePO4:Tb3+ nanorods. The combination of CDs and CePO4:Tb3+ nanorods was confirmed by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and so on. The mechanism of luminescence enhancement may be attributed to some aspects: the formation of hexagonal phase results in the increase of crystal field symmetry, and the energy transfer among CDs, Ce3+ and Tb3+ ions, which causes the Tb3+ ions in CDs@CePO4:Tb3+ nanorods to obtain more excited energy and less non-radiative attenuation compared to CePO4: Tb3+ nanorods. The luminescence enhancement strategy through combination of CDs would provide a simple and effective approach for other rare earth ions doped luminescent materials.
