Título: | Optical properties of organic/inorganic perovskite microcrystals through the characterization of Fabry-Pérot resonances |
Autor: | Ramiro-Manzano, F. CSIC ORCID; García-Aboal, R.; Fenollosa, Roberto; Biasi, S.; Rodríguez, Isabelle CSIC ORCID; Atienzar, Pedro CSIC ORCID ; Meseguer, Francisco CSIC ORCID | Fecha de publicación: | 17-ago-2020 | Editor: | Royal Society of Chemistry (UK) | Citación: | Dalton Transactions 49(36): 12798-12804 (2020) | Resumen: | A precise knowledge of the optical properties, specifically the refractive index, of organic/inorganic perovskites, is essential for pushing forward the performance of the current photovoltaic devices that are being developed from these materials. Here we show a robust method for determining the real and the imaginary part of the refractive index of MAPbBrthin films and micrometer size single crystals with planar geometry. The simultaneous fit of both the optical transmittance and the photoluminescence spectra to theoretical models defines unambiguously the refractive index and the crystal thickness. Because the method relies on the optical resonance phenomenon occurring in these microstructures, it can be used to further develop optical microcavities from perovskites or from other optical materials. | Versión del editor: | http://dx.doi.org/10.1039/d0dt02254c | URI: | http://hdl.handle.net/10261/226619 | DOI: | 10.1039/d0dt02254c | Identificadores: | doi: 10.1039/d0dt02254c issn: 1477-9234 |
