Autor: Guadalupe Garcia-Arellano, Gaëlle Trippé-Allard, Thomas Campos, Frédérick Bernardot, Laurent Legrand, Damien Garrot, Emmanuelle Deleporte, Christophe Testelin, Maria Chamarro

Publikováno v: Nanomaterials, Vol 12, Iss 9, p 1399 (2022)

In this work, we studied, at low temperature, the coherent evolution of the localized electron and hole spins in a polycrystalline film of CH3NH3PbI3 (MAPI) by using a picosecond-photo-induced Faraday rotation technique in an oblique magnetic field.

Photostability of 2D Organic-Inorganic Hybrid Perovskites

Autor: Yi Wei, Pierre Audebert, Laurent Galmiche, Jean-Sébastien Lauret, Emmanuelle Deleporte

Publikováno v: Materials, Vol 7, Iss 6, Pp 4789-4802 (2014)

We analyze the behavior of a series of newly synthesized (R-NH3)2PbX4 perovskites and, in particular, discuss the possible reasons which cause their degradation under UV illumination. Experimental results show that the degradation process depends a l

Preparations and Characterizations of Luminescent Two Dimensional Organic-inorganic Perovskite Semiconductors

Autor: Sanjun Zhang, Pierre Audebert, Yi Wei, Antoine Al Choueiry, Gaëtan Lanty, Antoine Bréhier, Laurent Galmiche, Gilles Clavier, Cédric Boissière, Jean-Sébastien Lauret, Emmanuelle Deleporte

Publikováno v: Materials, Vol 3, Iss 5, Pp 3385-3406 (2010)

This article reviews the synthesis, structural and optical characterizations of some novel luminescent two dimensional organic-inorganic perovskite (2DOIP) semiconductors. These 2DOIP semiconductors show a self-assembled nano-layered structure, havin

Using Low Temperature Photoluminescence Spectroscopy to Investigate CH3NH3PbI3 Hybrid Perovskite Degradation

Autor: Khaoula Jemli, Hiba Diab, Ferdinand Lédée, Gaelle Trippé-Allard, Damien Garrot, Bernard Geffroy, Jean-Sébastien Lauret, Pierre Audebert, Emmanuelle Deleporte

Publikováno v: Molecules, Vol 21, Iss 7, p 885 (2016)

Investigating the stability and evaluating the quality of the CH3NH3PbI3 perovskite structures is quite critical both to the design and fabrication of high-performance perovskite devices and to fundamental studies of the photophysics of the excitons.

Using chiral ammonium cations to modulate the structure of 1D hybrid lead bromide perovskites for linearly polarized broadband light emission at room temperature

Autor: Joanna M. Urban, Abdelaziz Jouaiti, Nathalie Gruber, Géraud Delport, Gaëlle Trippé-Allard, Jean-François Guillemoles, Emmanuelle Deleporte, Sylvie Ferlay, Damien Garrot

Publikováno v: Journal of Materials Chemistry C. 10:12436-12443

Low dimensional 1D enantiomerically pure and racemic lead bromide perovskite compounds have been structurally characterized. All compounds show broadband below-bandgap emission. They exhibit a significant degree of linear polarization at RT.
