Large sky blue perovskite LED, perhaps for lighting

Large-area sky-blue perovskite LEDs have been created at the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences. The precursor, a CsPb(Br0.84Cl0.16)3 solution using a custom solvent blend, was blade-coating onto a substrate where the substance crystallised into grains – halide amine additives controlled he growth of perovskite grains and passivate ...
