Rare-earth doped Phosphor BASED alkaline earth elements and silicon nitride manufacturing processes and converts emitting device comprising such Phosphor

摘要

FIELD: physics.SUBSTANCE: compounds, each containing at least one element from a group comprising rare-earth elements, alkali-earth elements, silicon and nitrogen, react at high temperature, where a small amount of oxygen is intentionally or unintentionally added. The obtained phosphor has general formula AESiNCO:RE, where AE is an alkali-earth element, RE is a rare-earth element and x is less than 1.EFFECT: phosphor has stable optical properties, longevity and high efficiency.9 cl, 3 dwg, 3 ex
