JI Le, WANG Ting-wei, ZHANG Qi-tu. Synthesis, Characterization and Fluorescence of a Bonding-type Eu-UA-siloxane Composite[J]. Chinese Journal of Luminescence, 2011,32(2): 134-137DOI:
a complex of rare earth europium (Eu) with Undecylenic acid (UA) was synthesized. Then the Eu-UA-siloxane composite was hydrosilylated from polyhydrosiloxane and the complex at the presence of Pt-catalyst
and characterized by means of FT-IR and 1H-NMR. The fluorescence spectra demonstrated that the composite was excited with a wavelength of 393 nm
exhibited the strongest emission at 616 nm. The fluorescence intensity of the composite increase linearly with the contents of europium increasing
no concentration quenching phenomenon was found.
