摘要： Novel orange 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, P; A3 is a 1−, 2−, or 3− anion, including F, Cl, and Br; and x is any value between 2.5 and 3.5, 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 orange phosphors are configured to emit visible light having a peak emission wavelength greater than about 565 nm. They have applications in white LED illumination systems, plasma display panels, and in orange and other colored LED systems.

The present phosphors may be represented by the formula a[Srx(M1)1-x]zSiO4●(1-a)[Sry(M2)1-y]uSiO5:Eu2+D, wherein M1 and M2 are at least one of a divalent metal such as Ba, Mg, Ca, and Zn, the values of a, x, y, z and u follow the following relationships: 0.6≦a≦0.85; 0.3≦x≦0.6; 0.85≦y≦1; 1.5≦z≦2.5; 2.6≦u≦3.3; and Eu and D each range from 0.001 to about 0.5. 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.

摘要： Disclosed herein are cerium doped, garnet phosphors emitting in the yellow region of the spectrum, and having the general formula (Y,A)3(Al,B)5(O,C)12:Ce3+, where A is Tb, Gd, Sm, La, Sr, Ba, Ca, and/or Mg, and substitutes for Y, B is Si, Ge, B, P, and/or Ga, and substitutes for Al, and C is F, Cl, N, and/or S, where C substitutes for O. Relative to a solid-state-reaction method, the instant co-precipitation methods provide a more homogeneous mixing environment to enhance the distribution of the Ce3+ activator in the YAG matrix. Such a uniform distribution has the benefit of an increased emission intensity. The primary particle size of the as-prepared phosphor is about 200 nm, with a narrow distribution.

摘要： Embodiments of the present invention are directed to the fluorescence of a nitride-based deep red phosphor having at least one of the following novel features: 1) an oxygen content less than about 2 percent by weight, and 2) a halogen content. Such phosphors are particularly 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 key feature of the present embodiments. The present 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+.
