Luminescent manganese-activated strontium barium chloro-aluminate phosphor composition process and lamp
Abstract
Abstract CERIUM SENSITIZED, MANGANESE-ACTIVATED STRONTIUM BARIUM CHLORO-ALUMINATE PHOSPHOR COMPOSITIONS ARE DISCLOSED WHEREIN THE FORMULA FOR THE PHOSPHOR CAN BE CHARACTERIZED AS FOLLOWS: SRXBAYCLZAL2O4-Z/2:MNUCEW WHEREIN THE SUM OF X AND Y IS BETWEEN 0.87 TO ABOUT 0.95, Z IS BETWEEN ABOUT 1.08 TO ABOUT 1.16, U AND W ARE EACH FROM ABOUT 0.005 TO 0.05. A PROCESS FOR PRODUCING THE PHOSPHOR COMPOSITION IS ALSO DISCLOSED WHEREIN SOURCES OF STRONTIUM, BARIUM, CHLORIDE, ALUMINATE, MANANOUS AND CEROUS IONS ARE UNIFORMLY ADMIXED BY BLENDING AND HEATED UNDER CONTROLLED TEMPERATURE CONDITIONS FOR A TIME SUFFICIENT TO PRODUCE THE LUMINESCENT PHOSPHOR COMPOSITION. ADDITIONALLY, AN IMPROVED LAMP UTILIZING A CERIUM-SENSITIZED, MANGANESE-ACTIVATED STRONTIUM BARIUM CHLOROALUMINATE PHOSPHOR IS DISCLOSED.
