TL;DR: This work shows that self-assembly based on robust DNA-origami constructs can precisely position single molecules laterally within sub-5 nm gaps between plasmonic substrates that support intense optical confinement.
Journal ArticleDOI

TL;DR: In this paper, femtosecond resolution diffuse X-ray scattering measurements were used to visualize excitation-induced strain fields in a prototypical member of the lead halide perovskites.
Journal ArticleDOI
Manganese doping for enhanced magnetic brightening and circular polarization control of dark excitons in paramagnetic layered hybrid metal-halide perovskites.

TL;DR: In this article, the magneto-optical properties of paramagnetic Ruddlesden-Popper hybrid perovskites were studied and it was shown that a dark exciton population is brightened by mixing with the bright excitons in the presence of a magnetic field.
Journal ArticleDOI
How Exciton Interactions Control Spin-Depolarization in Layered Hybrid Perovskites.
Sean A. Bourelle,Ravichandran Shivanna,Franco V. A. Camargo,Soumen Ghosh,Alexander J. Gillett,Satyaprasad P. Senanayak,Satyaprasad P. Senanayak,Sascha Feldmann,Lissa Eyre,Lissa Eyre,Arjun Ashoka,Tim Van De Goor,Haralds Abolins,Thomas Winkler,Giulio Cerullo,Richard H. Friend,Felix Deschler +16 more
TL;DR: Using circularly-polarised broadband transient absorption, time-resolved circular photoluminescence, and transient Faraday rotation spectroscopy, spin-dependent interactions have a significant impact on exciton energies and spin depolarisation times in layered Ruddlesden-Popper hybrid metal-halide perovskites.
Journal ArticleDOI
Optical control of exciton spin dynamics in layered metal halide perovskites via polaronic state formation

TL;DR: In this paper , the authors investigated the impact of strong coupling on the spin relaxation of excitons in the layered perovskite BA2FAPbI7 using a combination of cryogenic Faraday rotation and transient absorption spectroscopy, and reported an unexpected increase of the spin lifetime by two orders of magnitude at 77 K under photoexcitation with photon energy in excess of the exciton absorption peak.
