Halide Perovskite Nanocrystals@Graphene-based Sponges Hybrids: Synthesis, and Optoelectrical Properties

Hybrid organic–inorganic halide perovskites nanocrystals (HPNCs), such as CH3NH3PbX3 (X = Cl, Br, I), have recently experienced extraordinary development in optoelectronic applications due to their promising optical and electrical properties. Although most investigations have been mainly focused on improving and optimizing photovoltaics, light-emitting diodes, and photodetectors efficiencies of HPNCs, there is great interest and potential towards biological, biomedical, and environmental applications (e. g. biosensors, bioimaging). To accomplish this purpose, one possible strategy is to incorporate HPNCs into a highly porous host material to make a stable composite with enhanced quality. Therefore, we propose to use graphene-based sponges (GSs) as three-dimensional highly porous scaffolds to hold HPNCs, which has not been investigated before. We expect our strategy to result in a stable structure to enhance HPNCs stability as well as provide outstanding features of both GSs and HPNCs for applications in optoelectrical sensors or detectors. Results of the project are deliverable in research journals and can be filed as a patent.
