title: Mesoporous Aluminum Hydroxide Synthesized by a Single-Source Precursor-Decomposition Approach as a High-Quantum-Yield Blue Phosphor for UV-Pumped White-Light-Emitting Diodes.
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-1, while UV-white-LEDs integrating blue-emitting aluminum hydroxide and red-emitting CuInS2nanocrystals achieve high color-rendering-index values of 94.3 and luminous efficiency of 23.5 lm W-1.
