FERROUS-METAL-ALKALINE-EARTH-METAL SILICATE MIXED CRYSTAL PHOSPHOR AND LIGHT EMITTING DEVICE USING THE SAME

摘要

A ferrous-metal-alkaline-earth-metal mixed silicate based phosphor is used in form of a single component or a mixture as a light converter for a primarily visible and/or ultraviolet light emitting device. The phosphor has a rare earth element as an activator. The rare earth element is europium (Eu). Alternatively, the phosphor may have a coactivator formed of a rare earth element and at least one of Mn, Bi, Sn, and Sb. ® KIPO & WIPO 2009
