TUNABLE PHOSPHOR FOR LUMINESCENT

摘要

The present disclosure provides an illuminating system including a light emitting diode (LED); and a tunable luminescent material disposed approximate the light-emitting diode, wherein the tunable luminescent material includes alkaline earth metal (AE) and silicon aluminum nitride doped by a rare earth element (RE), formulated as (AE)Si6−pAlpN8, wherein p is a parameter defining a relative aluminum content in weight and p is greater than zero.
