      abstract     = {We compare the fluorescence properties of CsPbBr2Cl
                      nanocrystals, obtained via two distinct synthetic
                      procedures, and self-assembled into supercrystals using the
                      same antisolvent crystallization technique. By spatially
                      resolved fluorescence (lifetime) measurements we demonstrate
                      that the optical properties of the supercrystals depend on
                      the specific synthesis conditions of the constituting
                      nanocrystals. Using scanning electron microscopy,
                      small-angle X-ray scattering and nuclear magnetic resonance
                      spectroscopy, we find evidence that spatial fluctuations in
                      the supercrystal fluorescence correlate with the ligand
                      sphere of the nanocrystals. Specifically, homogeneous
                      surface passivation of the nanocrystals leads to consistent
                      interparticle distances and increased structural order
                      within the supercrystals, resulting in a uniform
                      fluorescence center wavelength and lifetime. The results of
                      this study emphasize the importance of the relationship
                      between crystalline structure and ligand configuration for
                      the control of the optical properties of lead halide
