摘要：

A novel blue-emitting Mg2La8(SiO4)(6)O-2:Ce3+ phosphor with apatite-type nanostructure has been successfully synthesized via a conventional solid-state reaction. X-ray diffraction (XRD) and photoluminescence (PL) spectroscopy were used to characterize the as-prepared samples. The phosphor exhibited an absorption band ranging from 220 to 400 nm in the ultraviolet range and generated bright blue emission at 425 nm and 510 nm under different excitation wavelengths. The critical Ce3+ quenching concentration (QC) was determined to be about 7 mol%, and the corresponding QC mechanism was verified to be the dipole-dipole interactions.
