摘要：
By using tetraethylorthosilicate (TEOS) and N-[3(trimethoxysilyl) propyl]-ethylenediamine as precursors, an inorganic-organic hybrid is synthesized, which is employed as a substrate to adsorption and hence spectroscopic study of the Eu(fod)(3) complex. Eu(fod)(3) and the silicon hybrid were mixed in stoichiometric amounts to produce samples with 1%, 5% and 10% (m/m) of adsorbed complex, with the matrices being pressed at 380 mPa for 0.5, 30 and 60 min. It is verified that the intensity of the D-5(0) --> F-7(2) emission band decreases as the percentage of complex is increased, which is interpreted as consequence of the modification of the coordination sphere of the complex.
