中文摘要	several new hybrid organic-inorganic langmuir-blodgett (lb) films containing europium-substituted hetero-polytungstate eu (xw11o39)(2)''(-) (x=ge, si, b) were successfully obtained using lb technique. when the heteropolytungstate anions are dissolved in the subphase, dimethyldioctadecylammonium bromide compression isotherms have been modified, which shows that the polyanions interact with the monolayer. y-type lb films were obtained from the systems. low-angle x-ray has shown that these lb films have well-defined lamella. the lb films were characterized by luminescence spectra and the characteristic luminescence behavior for europium-substituted heteropolytungstate complexes and their lb films were discussed. the results of excitation spectra indicate that the energy could be effectively transferred from ligands to the eu3+ ions in the lb films and the luminescence efficiency could be greatly increased. the results of luminescence spectra indicate that the formations of hybrid organic-inorganic lb films have a great effect on the luminescence of europium-substituted heteropolytungstate. the lifetime shortening was observed in lb films.
