Broadband emission from zero-dimensional Cs₄PbI₆ perovskite nanocrystals.

ABSTRACT: To overcome the drawbacks in three-dimensional (3D) perovskites, such as instability, surface hydration, and ion migration, recently researchers have focused on comparatively stable lower-dimensional perovskite derivatives. All-inorganic zero-dimensional (0D) perovskites (e.g., Cs₄PbX₆; X = Cl^-, Br^-, I^-) can be evolved as a high performing material due to their larger exciton binding energy and better structural stability. The clear understanding of carrier recombination process in 0D perovskites is very important for better exploitation in light-emitting devices. In this work, we comprehensively studied the light emission process in 0D Cs₄PbI₆ nanocrystals (NCs) and interestingly we observe intense white l
