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...
