Patent ID: 8318044

Claim:
A light emitting device, comprising: a light emitting diode configured to emit light; and a phosphor to change a wavelength of the light, the phosphor covering at least a portion of the light emitting diode, the phosphor comprising: a compound comprising a host lattice and a luminescent ion, the luminescent ion comprising at least one rare earth element within the host lattice, wherein the host lattice comprises first ions and oxygen, wherein a first portion of the first ions within the host lattice is substituted by divalent copper ions, wherein the compound emits light upon excitation with ultraviolet light or visible light, and wherein the host lattice comprises an aluminate, an antimonate, a germanate, any combination thereof, or at least one of an aluminate, an antimonate, a germanate in combination with a silicate or a germanate-silicate.
