| titleOfInvention | High efficiency polycrystalline phosphors and method of making same |
| abstract | A phosphor is provided that has a host material that is doped with a dopantnhaving the chemical structure XCl 3 , where X is a rare earth element or combination ofnelements. A free oxygen contributor is also added to provide the free oxygen necessarynto activate the rare earth dopant. The processing of the phosphor includes the heatingnof the phosphor in an overpressure environment of zinc, cadmium or tellurium. Thenheating is done in a two-temperature zone enclosed environment, so that impurities innthe phosphor powder are condensed out on the cooler surface. Alternatively, thendopant may be a material that is not a rare earth element, such as copper, tellurium,ncadmium, silver, potassium, manganese, magnesium, calcium, strontium, and barium. |
