摘要

Flexible luminescence materials have recently attracted increasing attention for their applications in the next generation intelligent devices. We developed an in situ fabrication approach to prepare MAPbBr(3) nanocrystals embedded in 2-methoxyethylacrylate (MEA) and N-isopropylacrylamide (NIPAM) copolymers matrix through controlling the crystallization of MAPbBr(3). The as-prepared nanocomposite films exhibited luminescent self-healing properties. By means of X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), and X-ray absorption fine structure spectroscopy (XAFS), we demonstrated that the copolymer acts as a unique medium to control the growth process of MAPbBr(3) perovskite nanocrystals. It is surface interaction between MAPbBr(3) nanocrystals and copolymer that play a key role in the luminescent and self-healing properties of nanocomposites. These work offers deep insights into the correlation between their structure and properties, which provides a novel approach to design the next generation smart optical materials.
