Warm-white light-emitting diode and its orange phosphor powder

摘要

The present invention discloses an orange phosphor powder having a rare-earth aluminate have garnet structure, which is characterized by that its chemical composition is added with compounds of the IV and V groups elements and the stoichiometry formula of the orange phosphor powder is (SigmaLn)3-xMeIVxAl5-ySiyO12-(x+y)N(x+y). Furthermore, the present invention also discloses a warm-white Light-emitting diode employing the orange phosphor powder.
