Abstract
Self-assembled perovskite nanocrystal superballs (SBs) represent a promising platform for generating cooperative quantum light emission, including superfluorescence (SF), amplified spontaneous emission and lasing, with critical applications in ultrafast lasers and quantum photonics. The packing density of nanocrystals within these superstructures is the key determinant governing their optical performance, influencing both the fluence threshold and temperature threshold for SF. While we have established that packing density can be tuned through ligand length and nanocrystal size variations, our current characterization lack quantitative precision and statistical robustness. To understand PSCs formation through the self-assembly process, synchrotron-based SAXS/WAXS measurements are critical.
