Abstract

Two-dimensional (2D) metal halide perovskites have emerged as promising materials for next-generation solar cells and light-emitting diodes thanks to their outstanding optoelectronic properties, facile tunability, and superior stability over their 3D counterparts. However, the detailed structure-property relationship of 2D perovskites underlying their optoelectronic properties has remained unclear. In this project, we design and synthesize a variety of 2D perovskite single crystals, in both Ruddlesden-Popper and Dion-Jacobson phases. We then use a combination of steady-state and time-resolved optical spectroscopy methods to characterize the exciton properties and dynamics, specifically focusing on how they are affected by changes in structural properties. Our results will help us develop a fundamental understanding of 2D perovskites and enable rational material design and development.
