Abstract: Embodiments of the present techniques provide a related family of phosphors that may be used in lighting systems to generate blue or blue-green light. The phosphors include systems having a general formula of: ((Sr1?zMz)1?(x+w)AwCex)3(Al1?ySiy)O4+y+3(x?w)F1?y?3(x?w) (I), wherein 0<x?0.10, 0?y?0.5, 0?z?0.5, 0?w?x, A is Li, Na, K, Rb, or Ag or any combinations thereof, and M is Ca, Ba, Mg, Zn, or Sn or any combinations thereof. Advantageously, phosphors made accordingly to these formulations maintain emission intensity across a wide range of temperatures. The phosphors may be used in lighting systems, such as LEDs and fluorescent tubes, among others, to produce blue and blue/green light. Further, the phosphors may be used in blends with other phosphors, or in combined lighting systems, to produce white light suitable for illumination.

Abstract: Phosphor compositions, blends thereof and light emitting devices including white light emitting LED based devices, and backlights, based on such phosphor compositions. The devices include a light source and a phosphor material as described. Also disclosed are phosphor blends including such a phosphor and devices made therefrom.

Abstract: A processing apparatus for use in a corrosive operating environment is provided. The apparatus includes a base substrate for placing a wafer thereon. The base substrate has a coefficient of thermal expansion. At least one electrode is embedded in or disposed on or under the base substrate. The electrode has a coefficient of thermal expansion in a range of from about 0.70 to about 1.25 times that of the base substrate coefficient of thermal expansion (CTE). At least one coating layer is disposed on the base substrate. The coating layer includes a composition capable of forming a calcium aluminate coating. The calcium aluminate coating layer is doped with one of MgO, CaO, CaF2 and mixtures thereof to control the CTE of the coating layer to match the CTE of the base substrate. The apparatus is exposed to a corrosive operating environment at a temperature range of from about 25 degrees Celsius to about 1500 degrees Celsius. A coated article and associated method are provided.

Abstract: A processing apparatus for use in a corrosive operating environment at a temperature range of 25-1500° C. is provided. The apparatus has an NZP or an NZP-type coating, which comprises a first composition, a second composition, and a metal cation. The first composition and the second composition form a crystalline structure with three-dimensional network of octahedra and tetrahedra linked by one or more shared atoms. The first composition comprises one or more of Zr, V, Ta, Nb, Hf, Ti, Al, Cr, or a metal of the Lanthanide series. The second composition comprises at least one of phosphorus, silicon, boron, vanadium or aluminum. The one or more shared atoms comprise at least one of oxygen, nitrogen, or carbon. The first composition and the second composition are related as shown by the formula (first composition)2 (second composition)x (shared atom)12-x. The metal cation is disposed within an interstitial site defined by the crystalline structure.
