Visible light sensitisation of europium(III) luminescence in a 9-hydroxyphenal-l-one complex

摘要

The 9-hydroxyphenal-l-one ligand forms stable 3 :1 complexes with trivalent lanthanides,in which it acts as an antenna suitable for the visible light excitation (up to 475 nm) of the trivalent europium ion.Trivalent lanthanide ions are known for their bright luminescence of high colorimetric purity.
