| Summary: | 碩士 === 元智大學 === 化學工程與材料科學學系 === 106 === In this study, different types of nano-perovskite materials were prepared by means of molecular arrangement design. Through the characterizations of transmission electron microscopy (TEM), atomic force micrograph (AFM) and synchrotron grazing-incidence x-ray diffraction (GIXRD) technique, the molecular arrangement and morphology of the nano-perovskite materials were studied to elucidate the interaction with polymer, in which the prepared perovskites exhibit excellent physical properties for optoelectronics. First, in this experiment, the addition of ligands reduces the repeated stacking of the perovskite material in the crystal arrangement to produce a special configuration of two-dimensional plate-like shape, which is identified by the analytical instruments mentioned herein. In addition, we demonstrated that the two-dimensional structure of perovskite material show the phenomenon of aggregation-induced emission, which is proved by the analysis of GIXRD technique. Secondly, based on the photo-responsibility of nano-perovskite materials, an novel optical photon writing–reading electrical erasing–read optical memory was proposed in this study, where the low-constant polymer was impregnated with discrete perovskite nanoparticle to make it have uniform dispersibility. And through the match of energy levels between the peroskite nanopaticle and the active semicondutor for effective charge transfer, the components of the optical response and charge storage capacity. Inspired by the above-mentioned interaction between nano-perovskite and semiconductor molecules, we, at present, are devoting to study the blends of nano-perovskite materials and conjugated polymer as semiconductor, aiming at improving the carrier mobility of organic transistor devices. At this point, through the basic research of perovskite materials, we understand the advantages of this material in many aspects of optoelectronic components. At present, we are developing a new generation of high-performance optoelectronic components with perovskite-based composite materials as the core design, and expect to expend their application in microelectronic components.
