英文摘要 | three series of yb3+-doped silica glasses containing different amounts of al2o3 and p2o5 were prepared successfully by using a sol-gel method. absorption, excitation and fluorescence spectra of yb2+ ions in these silica glasses as well as x-ray photoelectron spectra (xps) of yb4d were recorded and analysed systematically. it is found out that the addition of al3+ or p5+ ions has great influence on the redox state of ytterbium ions. with increasing al3+ ion contents in these silica glasses, more trivalent yb3+ ions are reduced to divalent yb2+. in contrast, the increase of p5+ ion contents greatly promotes divalent yb2+ ions to be oxidized to trivalent yb3+. the possible redox mechanisms have been explored and discussed in detail. the influence of al3+ and p5+ ion contents on the near-infrared luminescence intensity of yb3+ ions and cooperative luminescence of yb3+ ion pairs was also discussed. both the near-infrared luminescence intensity of yb3+ ions and cooperative luminescence of yb3+ ion pairs decrease gradually with increasing al3+ and p5+ ion contents. the decrease of cooperative luminescence of yb3+ ion pairs indicates a good dispersion effect of al3+ and p5+ ions on yb3+ ions in yb3+-doped silica glass. the results are useful for optimization of fabrication of the high quality yb3+-doped silica fiber by the composite design of yb-al-p co-doped silica glass. |
