| 英文摘要 | Well-dispersed and uniform Y2O3:Ln3+ (Ln3+ = Eu3+/Tb3+/Yb3+/Er3+/Tm3+) nanospheres have been successfully prepared at 180◦C via a facile hydrothermal route without any template, followed by a subsequent calcination process. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectrometer (EDS), transmission electron microscopy (TEM), photoluminescence (PL) spectra, and cathodoluminescence (CL) spectra as well as kinetic decay were employed to characterize the samples. It was found that the hydrothermal precursor could act as a template to obtain the corresponding oxide Y2O3 which inherited the original morphology of the hydrothermal precursor. The TEM and SEM images indicate that the samples consist of separated spheres with a mean diameter of about 260 nm. Under the excitation of ultraviolet (UV) light, 980-nm laser, and low-voltage electron beams, the Y2O3:Ln3+ phosphors all exhibited bright red, green and blue emissions, respectively, which were easily observed by naked eyes. The corresponding luminescent mechanism had been discussed. Due to the excellent PL (including up-conversion and down-conversion) and CL properties, multicolor tunable luminescence, ideal spherical shape, and cheap Y2O3 host, the as-prepared phosphors can potentially be used as fluorescent lamps, up-conversion fluorescent labels, and field emission display devices. |
