| 英文摘要 | al-doped and b, al co-doped sio2 xerogels with eu2+ ions were prepared only by sol-gel reaction in air without reducing heat-treatment or post-doping. the luminescence characteristics and mechanism of europium doping sio2 xerogels were studied as a function of the concentration of al, b, the europium concentration and the host composition. the emission spectra of the al-doped and b, al codoped samples all show an efficient emission broad band in the blue violet range. the blue emission of the al-doped sample was centered at 437 nm, whereas the b, al co-doped xerogel emission maximum shifted to 423 nm and the intensity became weaker. concentration quenching effect occurred in both the al-doped and b, al co-doped samples, which probably is the result of the transfer of the excitation energy from eu2+ ions to defects. the highest eu2+ emission intensity was observed for samples with the si(oc2h5)(4):c2h5oh:h2o molar ratio of 1:2:4.
