| 中文摘要 | in this paper, bpo4 and ba2+-doped bpo4 powder samples were prepared by the sol-gel process using glycerol and poly(ethylene glycol) as additives. the structure and optical properties of the resulting samples were characterized by x-ray diffraction (xrd), fourier transform infrared (ft-ir) spectroscopy, field emission scanning electron microscopy (fesem), diffuse reflection spectra, photoluminescence (pl) excitation and emission spectra, quantum yield, kinetic decay, and electron paramagnetic resonance (epr), respectively. it was found that the undoped bpo4 showed a weak purple blue emission (409 nm, lifetime 6.4 ns) due to the carbon impurities involved in the host lattice. doping ba2+ into bpo4 resulted in oxygen-related defects as additional emission centers which enhanced the emission intensity greatly (> 10x) and shifted the emission to a longer-wavelength region (lambda(max) = 434 nm; chromaticity coordinates: x = 0.174, y = 0. 187) with a bluish-white color. the highest emission intensity was obtained ;when doping 6 mol % ba2+ in bpo4, which has a quantum yield as high as 31%. the luminescent mechanisms of bpo4 and ba2+-doped bpo4 were discussed in detail according to the existing models for silica-based materials. |
