5-Ammoniumvaleric acid stabilized mixed-dimensional perovskite submicron platelets with white light emission

Low-dimensional Pb–Br and Pb–Cl perovskite single crystals have aroused considerable attention due to their broadband white-light emission. But their synthesis involving halogenation of organic amines, dissolution of lead oxide and a slow cooling process is quite complicated. Herein, we report white...

description Low-dimensional Pb–Br and Pb–Cl perovskite single crystals have aroused considerable attention due to their broadband white-light emission. But their synthesis involving halogenation of organic amines, dissolution of lead oxide and a slow cooling process is quite complicated. Herein, we report white light emission from mixed-dimensional AVA(x)(MAPbCl(3)) perovskite submicron platelets formed by one-step solution processing. It is found that the presence of 5-ammoniumvaleric acid (5-AVA) with a zwitterionic functional group is crucial for modulating the morphology and structural dimensionality of perovskites. Importantly, AVA(x)(MAPbCl(3)) perovskites exhibit distinctive structural dimensionality dependent broadband emission, indicating the formation of self-trapped excited states. The AVA(2)(MAPbCl(3)) perovskite exhibits white-light emission with a color rendering index (CRI) of 85 and a correlated color temperature (CCT) of 8624 K, yielding “cold” white light. Moreover, the mixed-dimensional perovskite exhibits good stability for more than 30 days. With this report, we aim to provide a facile approach for synthesizing stable low-dimensional perovskite nanostructures for making advanced optoelectronic devices.
