摘要： Novel green phosphors are disclosed having the comprise silicate-based compounds having the formula (Sr,A1)x(Si,A2)(O,A3)2+x:Eu2+, where A1 is at least one divalent cation (a 2+ ion) including Mg, Ca, Ba, or Zn, or a combination of 1+ and 3+ cations; A2 is a 3+, 4+, or 5+ cation, including at least one of B, Al, Ga, C, Ge, N, and P; A3 is a 1−, 2−, or 3− anion, including F, Cl, Br, and S; and x is any value between 1.5 and 2.5, both inclusive. The formula is written to indicate that the A1 cation replaces Sr; the A2 cation replaces Si, and the A3 anion replaces O. These green phosphors are configured to emit visible light having a peak emission wavelength greater than about 480 nm. They have applications in green illumination systems, red-green-blue backlighting systems, white LEDs, and plasma display panels (PDPs).

D is an anion selected from the group consisting of F, Cl, Br, S, and N, and at least some of the D anion replaces oxygen in the host silicate lattice of the phosphor. The present yellow phosphors have applications in high brightness white LED illumination systems, LCD display panels, plasma display panels, and yellow LEDs and illumination systems.
