TL;DR: Two-dimensional electronic spectroscopy is applied to probe the timescale and amplitude of the electronic gap correlations in CsPbI3 perovskite nanocrystals via homogeneous lineshape dynamics to reveal irreversible, diffusive dynamics that are qualitatively inconsistent with the coherent dynamics in covalent solids such as CdSe quantum dots.
Seeing Multiexcitons through Sample Inhomogeneity: Band-Edge Biexciton Structure in CdSe Nanocrystals Revealed by Two-Dimensional Electronic Spectroscopy.
TL;DR: It is shown that the band-edge biexciton structure must consist of a discrete manifold of electronic states that feature distinctive binding energies, which have direct implications for optical gain thresholds and efficiency droop in light-emitting devices and provide experimental measures of many-body physics in nanostructures.

Investigating the electronic structure of confined multiexcitons with nonlinear spectroscopies.
Samuel Palato,Hélène Seiler,Harry Baker,Colin Sonnichsen,Patrick J. Brosseau,Patanjali Kambhampati +5 more
TL;DR: This work reports on the investigation of the electronic structure of MX in colloidal CdSe QDs using time-resolved photoluminescence, state-resolving pump-probe, and two-dimensional spectroscopies and outlines the limits of the simple concept of binding energy.

Emitting State of Bulk CsPbBr3 Perovskite Nanocrystals Reveals a Quantum-Confined Excitonic Structure
TL;DR: In this paper, the authors present time-resolved photoluminescence (t-PL) measurements on bulk CsPbBr₃ nanocrystals (NCs).

Fifth-order two-quantum absorptive two-dimensional electronic spectroscopy of CdSe quantum dots.
TL;DR: Two-quantum variants of two-dimensional electronic spectroscopy (2DES) have previously been used to characterize multi-exciton interactions in molecules and semiconductor nanostructures though many implementations are limited by phasing procedures or non-resonant signals.
