Synthesis of europium(III) phenanthroline-β-diketonate silicon-containing complex. Photoluminescence in solution and in sol-gel film
A phenanthroline benzoyltrifluoroacetonate europium complex showing a bright red photoluminescence at a wavelength 616 nm was synthesized by reacting 3-isocyanatopropyltriethoxysilane with anhydrous europium(III) tris(benzoyltrifluoroacetonate) and then with phenanthroline.
