Synthetic method for Nitride red phosphor

摘要

the present invention is the surface area Activated carbon with CRN (carbothermal reduction and nitridation) by atmospheric pressure under way economical use of raw powder of high purity oxides Sr ₂ Si ₅ N _{8 and a method of manufacturing the red phosphor relates . More particularly, the present invention is directed to a conventional incandescent lamp , UV fluorescent lamp according to an alternative to the fluorescent material that can be used for lighting and display to the next generation by a Blue LED excitation light that a light red nitride phosphor and a preparation method thereof .}
