Impact of Aging Temperatures on the Ostwald Ripening Crystallization and Optical Properties in CsPbBr₃ Nanocrystals.

ABSTRACT: Despite the exceptional optical properties of CsPbBr₃ (CPB) nanocrystals (NCs), maintaining their long-term colloidal and structural reliability remains a significant barrier to commercialization. The influence of environmental conditions on Ostwald ripening and its effects on the crystal structure and optical behavior of CPB NCs has not been thoroughly investigated. In this work, CPB NCs were synthesized using a high-temperature hot-injection method and dispersed in n-heptane. They were evaluated by integrating population balance theory-based crystallization kinetic studies with experimental measurements over 30 days at aging temperatures of -20, 25, and 70 °C, which represent different storage conditions. The size and crystal lattice of CPB NCs dispersed in n-hep
