    Abstract: Novel phosphor systems for a white LED are disclosed. The phosphor systems are excited by a non-visible to near-UV radiation source having an excitation wavelength ranging from about 250 to 420 nm. The phosphor system may comprise one phosphor, two phosphors, and may include optionally a third and even a fourth phosphor. In one embodiment of the present invention, the phosphor is a two phosphor system having a blue phosphor and a yellow phosphor, wherein the long wavelength end of the blue phosphor is substantially the same wavelength as the short wavelength end of the yellow phosphor. Alternatively, there may be a wavelength gap between the yellow and blue phosphors. The yellow phosphor may be phosphate or silicate-based, and the blue phosphor may be silicate or aluminate-based. Single phosphor systems excited by non-visible radiation are also disclosed. In other embodiments of present invention, a single phosphor is used to produce white light illumination, the single phosphor having a broad emission spectrum with a peak intensity ranging from about 520 to 560 nm.

    Abstract: A nitride-based deep red phosphor having at least one of the following features: 1) an oxygen content less than about 2 percent by weight, and 2) a halogen content. Such phosphors are useful in the white light illumination industry, which utilizes the so-called "white LED." The selection and use of a rare earth halide as a raw material source of not only the activator for the phosphor, but also the halogen, is a feature of the present embodiments. The phosphors have the general formula MaMbBc(N,D):Eu2+, where Ma is a divalent alkaline earth metal such as Mg, Ca, Sr, Ba; Mb is a trivalent metal such as Al, Ga, Bi, Y, La, and Sm; and Mc is a tetravalent element such as Si, Ge, P, and B; N is nitrogen, and D is a halogen such as F, Cl, or Br. An exemplary compound is CaAlSi(N1-xFx): Eu2+.

    Abstract: Embodiments of the invention are directed toward white light illumination systems (so called 'white LEDs') that comprise a multi-chip excitation source and a phosphor package. In a two-chip source, the two LEDs may be UV-emitting and blue emitting, or blue-emitting and green-emitting. The phosphor package is configured to emit photoluminescence in wavelengths ranging from about 440 nm to about 700 nm upon co-excitation from the first and second radiation sources. The photoluminescence emitted by the phosphors is at least 40 percent of the total power in the white light illumination, and the portion of the total power in the white light illumination contributed by the first and second radiation sources (LEDs) is less than about 60 percent. This ratio can vary in alternative embodiments, and includes 50/50, 60/40, 70/30, and 80/20, respectively. The white light illumination emitted by the system has in one embodiment a color rendering index (CRI) greater than about 90.
