Perovskite materials have emerged as a promising candidate for application in solar energy harvesting. However, after the successful synthesis of highly emissive nanostructures made from all-inorganic Cesium-Lead-Halide perovskites, this class of materials became of interest to lighting applications. In a recent paper by Nagamine et.al., published in The Journal of Physical Chemistry Letters, we have …

Investigating nonlinear optical properties in organic dyes contributes to the understanding of the molecular structure and drives the development of novel highly nonlinear optical materials. In this study, which is part of Thiago Cardoso and Leonardo Barros´s undergraduate project, we have shown a way to obtain record high two-photon absorption cross section in visible emitting …

In our most recent paper, published by ACS Nano, we show that all-inorganic perovskites quantum dots exhibit unprecedentedly high multiexciton Coulomb interactions, resulting in nearly one order of magnitude higher Auger rate and biexciton binding energies as large as 100 meV.
