Stable green and red dual-color emission in all-inorganic halide-mixed perovskite single microsheets.

ABSTRACT: Recently, all-inorganic perovskites have attracted tremendous attention due to their excellent optoelectronic properties and extensive potential applications. However, these perovskites usually show a single emission wavelength because of the high ionic migration. Herein, we synthesized all-inorganic halide-mixed perovskite CsPbBr _x I_3-x microsheets with high crystal quality using the anti-solvent solution method and observed extraordinary green and red dual-color emission in single CsPbBr _x I_3-x microsheets. Power dependent PL spectra reveal excitonic and defect related recombination features of CsPbBr₃ and CsPbI₃ for the green and red emission. Temperature dependent PL spectra indicated a distin
