Synthesis and characterization of europium (III), terbium (III) complexes and their mixture for making white light emission powder

The enhanced luminescence of lanthanide complexes coordinated to antenna ligands has potential applications for developing devices like screens and lamps. Herein, three β -diketone were incorporated into Eu(III) Tb(III) metals synthesize five complexes. Their properties in solid state the energy levels electronic states recorded probed by UV–vis fluorescence spectroscopies. Under UV light, a white-light emission powder was observed mixing red-emission europium green-emission terbium complexes, with blue-emission laundry powder. composition tuned using spectroscopic analysis CIE 1931 color diagram.
