Novel Eu²⁺-Activated Yellow-Emitting Sr₈MgLu(PO₄)₇ Phosphors for White-Light Near-Ultraviolet LEDs

Abstract

Since the first reports on bright-blue-emitting InGaN-based light-emitting diodes (LEDs), efforts have contin-ually been made to realize solid-state lighting devices.White LEDs have attracted much attention because theyhave high efficiencies, long operational lifetimes, goodmaterial stabilities, low power consumption, and mercury-free.
