Manganese activated zinc silicate phosphor

摘要

A new and improved manganese activated zinc silicate phosphor is described. The phosphor has cations consisting essentially of zinc, silicon, manganese, and tungsten. The phosphor has an absolute reflectance less than or equal to 13.5% at 275 nm, an absolute reflectance equal to or greater than 80% at 350 nm, and a surface area from about 0.3 m2/gm to about 0.4 m2gm.
