Excitonic Energy

We present transient microscopy measurements of interlayer energy transport in (PEA)<sub>2</sub>PbI<sub>4</sub> perovskite. We find efficient interlayer exciton transport (0.06 cm<sup>2</sup>/s), which translates into a diffusion length that exceeds 100 nm and a sub-ps timescale for energy transfer. While still slower than in-plane exciton transport (0.2 cm<sup>2</sup>/s), our results show that excitonic energy transport is considerably less anisotropic than charge-carrier transport for 2D perovskites.

Excitonic energy transfer is a versatile mechanism by which colloidal semiconductor nanocrystals can interact with a variety of nanoscale species. This feature article will discuss the latest research on the key scenarios under which semiconductor nanocrystals can engage in energy transfer with other nanoparticles, organic fluorophores, and plasmonic nanostructures, highlighting potential technological benefits to be gained from such processes.
