    Abstract

    Sr2SiO4: Eu2+ phosphor was prepared by a modified sol-gel method. The structure and the composition of the phosphor nanorods were characterized by powder X-ray diffraction (XRD) and energy dispersion spectrum (EDS). Field-emission scanning electron microscopy (FE-SEM) and photo-luminescent spectra were used to characterize the shape and the luminescent properties of phosphor particles. One-dimensional Sr2SiO4: Eu2+ nanorods were obtained, which shows intense blue-green emission under the excitation of near ultraviolet (n-UV) light (275-425 nm). It indicates that Sr2SiO4: Eu2+ phosphors are promising blue-green candidates for the n-UV white LEDs.
