Abstract
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<sup>-1</sup> , while UV-white-LEDs integrating blue-emitting aluminum hydroxide and red-emitting CuInS<sub>2</sub> nanocrystals achieve high color-rendering-index values of 94.3 and luminous efficiency of 23.5 lm W<sup>-1</sup> .
