Strongly emissive (photoluminescence quantum yield up to 65%), thermally stable aluminum hydroxide blue phosphors are synthesized by a single‐source precursor‐decomposition approach. Blue‐emitting UV‐pumped light‐emitting diodes (LEDs) based on the aluminum hydroxide phosphor reach luminous efficiency of 27.5 lm W −1 , while UV‐white‐LEDs integrating blue‐emitting aluminum hydroxide and red‐emitting CuInS 2 nanocrystals achieve high color‐rendering‐index values of 94.3 and luminous efficiency of 23.5 lm W −1 .
