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
3+
concentration of 0.01 give the strongest emission. The luminescence mechanism of Na
