Abstract: A phosphor composition is derived from combining K2SiF6:Mn4+ in solid form with a saturated solution of a manganese-free complex fluoride including a composition of formula I: A3[MF6], 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: A3[MF6] has a water solubility lower than a water solubility of K2SiF6. A lighting apparatus including the phosphor composition is also provided.

Abstract: 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.
