Locking Broadband Bi 3+ Luminescence Color From 6 to 423 K

ABSTRACT Wide‐temperature color‐stable luminescence is a critical requirement for high‐performance phosphor‐converted light‐emitting diodes (pc‐LEDs). However, broadband emitters, particularly Bi 3+ ‐activated phosphors, universally suffer from thermally induced spectral drift. T...
