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

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.

Dynamique du champ proche plasmonique et génération de dérivés réactifs de l'oxygène par des nanobâtonnets d'or sous irradiation laser ultrabrève

Les nanoparticules d'or sont connues pour leurs propriétés optiques remarquables liées à la résonance plasmon de surface localisée (LSPR pour localized surface plasmon resonance). Elles absorbent alors efficacement le rayonnement incident, le…

Unexpected Anisotropy of the Electron and Hole Landé g-Factors in Perovskite CH3NH3PbI3 Polycrystalline Films

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…

Metallo-dielectric metasurfaces for thermal emission with controlled spectral bandwidth and angular aperture

We introduce thermal metallo-dielectric metasurfaces as mid IR sources. The emitter is a lossy metal. The spectral and angular emission is controlled using a periodic array of high refractive dielectric resonators. We introduce a design that allows…

Comparative analysis of recirculating and collimating cesium ovens

We have performed a study of several cesium oven designs. A comparison between recirculating (or sticking-wall) and collimating (or re-emitting-wall) ovens is made in order to extract the most efficient design in terms of beam brightness…
