| Sumario: | <p id="p1">Two-dimension (2D) hybrid organic-inorganic perovskites (HOIPs) are formed naturally multiple-quantum-well structures with a much larger carrier binding energy, which possess stable excitons even at room temperature. In addition, 2D HOIPs allow us to exfoliate them into ultrathin flakes and stack them into various heterostructures, extending their photophysical properties. Therefore, 2D HOIPs are promising candidates for optoelectronic device applications, such as light-emitting diodes, lasing, etc. In this chapter, a summary of the crystal structures of 2D HOIP crystals and their heterostructures, excitonic properties, and the current research progress of the 2D HOIPs and their heterostructures are revealed. Next, high-pressure technology will be studied in detail on the effective engineering of crystal structures and exciton properties of 2D HOIPs toward significantly optimizing their functionalities. Finally, a summary is given, and the high-pressure strategy toward manipulation of 2D perovskite-based heterostructures is rationalized for next-generation high-performance excitonic devices.</p> |
