A process for synthesizing a manganese doped phosphor of formula I: A[MF]:Mnis presented. The process includes contacting a first solution with a second solution and a third solution in the presence of a plurality of inert particles. The first solution and the second solution include a composition of formula II: A[MnF]. The third solution includes a source of M, where A is Li, Na, K, Rb, Cs, or combinations thereof; M is Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, or combinations thereof; x is an absolute value of a charge of the [MF] ion; and y is 5, 6 or 7.

Processes for synthesizing red-emitting phosphors and related red-emitting phosphors

A phosphor composition is derived from combining KSiF:Mnin solid form with a saturated solution of a manganese-free complex fluoride including a composition of formula I: A[MF], where A is selected from Na, K, Rb, and combinations thereof and M is selected from Al, Ga, In, Sc, Y, Gd, and combinations thereof. The composition of formula I: A[MF] has a water solubility lower than a water solubility of KSiF. A lighting apparatus including the phosphor composition is also provided.

Moisture-resistant phosphor compositions and associate methods

A method for joining a metal component to a ceramic component is presented. The method includes disposing a metallic barrier layer on a metallized portion of the ceramic component, and joining the metal component to the metallized portion of the ceramic component through the metallic barrier layer. The metallic barrier layer comprises nickel and a melting point depressant. The metallic barrier layer is disposed by a screen printing process, followed by sintering the layer at a temperature less than about 1000 degrees Celsius. A sealing structure including a joint between a ceramic component and a metal component is also presented.

Method for joining ceramic to metal, and sealing structure thereof

A gas sensor is disclosed. The gas sensor includes a gas sensing layer, at least one electrode, an adhesion layer, and a response modification layer adjacent to said gas sensing layer and said layer of adhesion. A system having an exhaust system and a gas sensor is also disclosed. A method of fabricating the gas sensor is also disclosed.

Gas sensor and method of making

A gas sensor is disclosed. The gas sensor includes a gas sensing layer including doped oxygen deficient tungsten oxide and a dopant selected from the group consisting of Re, Ni, Cr, V, W, and a combination thereof, at least one electrode positioned within a layer of titanium, and a response modification layer. The at least one electrode is in communication with the gas sensing layer and the gas sensing layer is capable of detecting at least one gas selected from the group consisting of NO, NO, SOO, HO, and NH. A method of fabricating the gas sensor is also disclosed.
