Configuration Effect on Exciton Dynamics of Zinc Chlorin Aggregates

Excitonic energy transfer among zinc chlorin molecules is significant for photovoltaic process because of their high sensitivities of harvesting sunlight. Zinc chlorin monomers and dimers can be synthesized experimentally, and...

Efficient Interlayer Exciton Transport in Two-Dimensional Metal-Halide Perovskites.

We present transient microscopy measurements of interlayer energy transport in (PEA)₂PbI₄ perovskite. We find efficient interlayer exciton transport (0.06 cm²/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 cm²/s), our results show that excitonic energy transport is considerably less anisotropic than charge-carrier transport for 2D perovskites.

Towards a spectroscopic protocol for unambiguous detection of quantum coherence in excitonic energy transport

We propose a witness for quantum coherence in EET that can be extracted directly from two-pulse pump–probe spectroscopy experimental data.
