Quantum Dots: CsPbX₃ Quantum Dots for Lighting and Displays: Room‐Temperature Synthesis, Photoluminescence Superiorities, Underlying Origins and White Light‐Emitting Diodes (Adv. Funct. Mater. 15/2016)

A room-temperature supersaturated recrystallization method is developed on page 2435 by H. Zeng and co-workers, to rapidly synthesize all-inorganic halide perovskite quantum dots with blue, green, and red luminescent quantum yields of 70–95% and line-widths less than 35 nm. The origins of the optical superiority are proposed to be the 40 meV exciton binding energy, surface self-passivation, and quantum-well band alignment, leading to promising potential in healthy lighting and wide-color-gamut displays.
