Non-Rare-Earth BaMgAl_10–2xO₁₇:xMn⁴⁺,xMg²⁺: A Narrow-Band Red Phosphor for Use as a High-Power Warm w-LED

Owing to its low cost and admirable luminescent characteristics for use in warm white-light-emitting diode (w-LED) applications, the non-rare-earth Mn4+-activated red phosphor has emerged as a potent competitor of commercial Eu2+-doped nitrides in recent years. In this work, the novel red-emitting phosphor BaMgAl10–2xO17:xMn4+,xMg2+ is successfully synthesized, which exhibits bright and narrow-band luminescence peaking at 660 nm with a full...
