    摘要: A fluorescent lamp including a phosphor layer including (Y1-x-yGdx)AlO3:EU3+y, wherein 0.4≦x≦0.7 and 0≦y≦0.1, and at least one of each of a green and blue emitting phosphor. The resulting lamp will exhibit a white light having a color rendering index of preferably 90 or higher with a correlated color temperature of from 2500 to 10000 Kelvin. The use of (Y1-x-yGdx)AlO3:Eu3+y in phosphor blends of lamps results in high CRI light sources with increased stability and acceptable lumen maintenance over, the course of the lamp life.

    摘要: A phosphor comprises an oxide that comprises: (a) at least an element selected from the group consisting of phosphorus and boron; (b) at least a metal selected from the group consisting of elements of Group IIIA, elements of Group IVA, and elements of the lanthanide series; which oxide is co-activated with Ce3+ and Tb3+. In one embodiment, a phosphor comprises lanthanum and gadolinium phosphate and/or borate co-activated with cerium and terbium. A phosphor of the present invention has low emission of UV radiation having wavelengths longer than about 250 nm, thus efficiently uses exciting UV having shorter wavelengths. The phosphor is used in light source that comprises a UV radiation source to convert efficiently UV radiation to visible light.
