摘要： A phosphor includes a crystal phase of a formula (Ln,Ca,Ce)3+αSi6N11. In this formula, α is from −0.1 to 1.5, inclusive. When an object color of the phosphor is expressed by the L*a*b* color system, the value of (a*2+b*2)1/2 satisfies 71≦(a*2+b*2)1/2. Also in the formula, Ln is La, Gd, Lu, Y, Sc, or any combination of these. When the phosphor is excited with light having a wavelength of 455 nm, it emits a color wherein x is from 0.400 to 0.570 inclusive, and y is from 0.420 to 0.590, inclusive, as expressed in the CIE standard coordinate system.

摘要： The disclosure is directed to glass frits materials containing phosphors that can be used in LED lighting devices and for methods associated therewith for making the phosphor containing frit materials. Suitable non-lead glasses have a composition, in mol %, in the range of 20-24% K2O, 8-12% ZnO, 2-6% Al2O3, 35-41% B2O3 and 22-28 SiO2. Suitable leaded glasses have a composition, in wt %, in range of 72-79% PbO, 8-13% Al2O3, 8-13% B2O3, 2-5% SiO2 and 0-0.3% Sb2O3. Commercial high-lead glass can be used in practicing the disclosure. Among the unique advantages are the ability to blend two or more phosphors within the same frit layer which will yield a multi-phosphor-containing glass after firing; the ability to deposit the phosphor onto a substrate into a desired geometric pattern; and the fluorescing layer can be applied to the active plane, with the glass serving as protective substrate.
