CsCu₂I₃ Nanocrystals: Growth and Structural Evolution for Tunable Light Emission.

ABSTRACT: CsCu₂I₃ mixed with Cs₃Cu₂I₅ has shown potential applications as white-light-emitting materials, while their growth, structural evolution behaviors, and their impact on photoluminescence of CsCu₂I₃ nanocrystals (NCs) are still not known. In this work, we investigated the growth and structural evolution of CsCu₂I₃ nanocrystals with increasing reaction temperature. At low temperature and in the presence of a high dosage of oleic acid and oleylamine, Cs₃Cu₂I₅ nanoparticles, rather than CsCu₂I₃ NCs, preferred to form in the hot-injection reaction system. Increasing the reaction temperature promoted the formation of CsCu₂I₃
