Abstract:
A phosphor blend for a compact fluorescent lamp is described wherein the phosphor blend comprises a green-emitting Tb 3+ phosphor, a Y 2 O 3 :Eu 3+ phosphor, a Sr 6 BP 5 O 20 :Eu 2+ phosphor, a Mg 4 GeO 5.5 F:Mn 4+ phosphor, and optionally a BaMgAl 11 O 17 :Eu 2+ phosphor, wherein the blend contains from 1% to 20% by weight of the Sr 6 BP 5 O 20 :Eu 2+ phosphor and from 5% to 30% by weight of the Mg 4 GeO 5.5 F:Mn 4+ phosphor. A compact fluorescent lamp having a phosphor coating containing the phosphor blend produces a light that is perceived as more pleasing than the light produced by standard compact fluorescent lamps.

Abstract:
A lighting apparatus for emitting white light including a semiconductor light source emitting radiation with a peak at from about 250 nm to about 500 nm; a first phosphor having a peak emission between about 450 and 550 nm; and a second phosphor having a peak emission between about 615 and 670 nm; wherein the overall emission spectrum of the lighting apparatus has a depression between about 550 and 615 nm, said depression extending to between about 5% and 25% of the highest intensity of the emission spectrum of the lighting apparatus in the region from 400 to 700 nm. In this apparatus, the red-green color contrast is increased versus the referent illuminant.
Abstract:
A method for forming a powder phosphor electroluminescent display (100, 600) includes forming a dielectric film (140, 630) on a plurality of sides of an uncoated phosphor layer (150, 640, 640', 640"), wherein the dielectric film (140, 630) is formed via a polymer multilayer process.

Abstract:
This invention relates to luminescent materials for ultraviolet light or visible light excitation containing lead and/or copper doped chemical compounds. The luminescent material is composed of one or more than one compounds of aluminate type, silicate type, antimonate type, germanate/or germanate- silicate type, and/or phosphate type. Accordingly, the present invention is a good possibility to substitute earth alkaline ions by lead and copper for a shifting of the emission bands to longer or shorter wave length, respectively. Luminescent compounds containing copper and/or lead with improved luminescent properties and also with improved stability against water, humidity as well as other polar solvents are provided. The present invention is to provide lead and/or copper doped luminescent compounds, which has high color temperature range about 2,00OK to 8,000K or 10,000K and CRI over 90.
