High‐quality hybrid halide perovskite nanocrystals are fabricated through a simple, versatile, and efficient two‐step process involving a dry step followed by a ligand‐assisted liquid‐phase exfoliation step. The emission wavelength of the resulting nanocrystals can be tuned either through composition by varying the halide content or by reducing their thickness.
