Photophysics of Low-Dimensional Halide Perovskites

Halide perovskites possess outstanding optoelectronic properties favorable for applications as highly efficient emitters in perovskite light-emitting devices (PeLEDs), lasers as well as quantum emitters. Their versatile structures and diverse dimensionalities afford new levers for tunning their photophysical properties. In this talk, I will distill some of the underpinning photophysical mechanisms in low-dimensional emitters such as layered Ruddlesden Popper perovskites and colloidal perovskite nanocrystals.
