Precise Control of Green to Blue Emission of Halide Perovskite Nanocrystals Using Terbium Chloride as Chlorine Source

Precise Control of Green to Blue Emission of Halide Perovskite Nanocrystals Using Terbium Chloride as Chlorine Source

CsPbCl<sub>x</sub>Br<sub>3-x</sub> nanocrystals were prepared by ligand-assisted deposition at room temperature, and their wavelength was accurately adjusted by doping TbCl<sub>3</sub>. The synthesized nanocrystals were monoclinic and the morphology was almost unc...
