Novel aluminum-silicate based orange -red phosphors, with mixed di- and trivalent cations are disclosed. The phosphors have the formula (Sr<SUB>1-x-y</SUB>M<SUB>x</SUB>T<SUB>y</SUB>)<SUB>3-m</SUB>Eu<SUB>m</SUB>(Si<SUB>1_z</SUB>Al<SUB>z</SUB>)0<SUB>5</SUB>, where M is at least one of Ba, Mg, Ca, and Zn in an amount ranging from O=x=O.4. T is a trivalent metal in an amount ranging from 0<y<0. This phosphor is configured to emit visible light having a peak emission wavelength greater than about 580 nm. The phosphors may contain a halogen anion such as F, Cl, and Br, at least some of which is substitutionally positioned on oxygen lattice sites. The present aluminum- silicate phosphors have applications in white and orange-red illumination systems, as well as plasma display panels. |
