Abstract
A Europium beta-diketonate molecule comprises Europium with ligands dibenzoylmethane, 1,10-phenanthroline, and methoxide. The molecule is photoluminescent, absorbing light from the ultraviolet region through the blue region and emitting red light characteristic of trivalent europium. The molecule may be used, for example, as a phosphor in a phosphor-converted light-emitting diode.
Claims21
A photoluminescent molecule comprising one or more rare earth ions selected from the group consisting of Europium, Gadolinium, Terbium, and mixtures thereof, each with ligands of dibenzoylmethane, 1,10-phenanthroline, and methoxide.
A light emitting device, comprising:
- a semiconductor light emitting device emitting primary light;
- and
- a phosphor material capable of absorbing at least a portion of the primary light and in response emitting secondary light having a wavelength longer than a wavelength of the primary light;
- wherein the phosphor material comprises a photoluminescent molecule comprising one or more rare earth ions selected from the group consisting of Europium, Gadolinium, Terbium, and mixtures thereof, each with ligands of dibenzoylmethane, 1,10-phenanthroline, and methoxide
A molecule comprising one or more rare earth ions selected from the group consisting of Europium, Praseodymium, Gadolinium, Terbium, and mixtures thereof, each with ligands of dibenzoylmethane, 1,10-phenanthroline, and methoxide.
