Abstract

∶Sb

phosphors were prepared with a sol-gel method. The samples were characterized with X-ray diffraction

reflectance spectra

emission and excitation spectra. The phosphor can be excited with ultrovilet light in the range of 250~320 nm and give intensitive emission in the range of 410~550 nm. The maximum emission and excitation wavelength is 470 nm and 280 nm

respectively. The optimized sintered temperature is 800 ℃ and samples with a Sb

concentration of 0.01 give the strongest emission. The luminescence mechanism of Na

∶Sb

phosphors were also briefly discussed.
