Using Low Temperature Photoluminescence Spectroscopy to Investigate CH3NH3PbI3 Hybrid Perovskite Degradation

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…

Excitonic properties and ultrafast carrier dynamics in hybrid organic-perovskites

Due to their high potentiality for photovoltaic applications or coherent light sources, a renewed interest in hybrid organic perovskites (HOPs) has emerged since 2012. HOPs can be arranged in such a way that carriers are free to move at 3D or at 2D…

Propriétés optiques comparées des monocristaux et couches minces de pérovskites hybrides organiques-inorganiques 3D

En dépit de l’incroyable engouement suscité par les pérovskites hybrides 3D, lié à leurs performances comme matériau absorbeur dans les cellules photovoltaïques, les études fondamentales sur la photophysique de ces composés sont encore peu…

Giant Amplification of Photoswitching by a Few Photons in Fluorescent Photochromic Organic Nanoparticles

Controlling or switching the optical signal from a large collection of molecules with the minimum of photons represents an extremely attractive concept. Promising fundamental and practical applications may be derived from such a photon-saving…

Dual electrochemical modulation of reflectivity and luminescence on plasmonic gratings investigated by fluorescence microscopy coupled to electrochemistry

By coupling fluorescence microscopy and electrochemistry at plasmonic electrodes, a first example of simultaneous dual electrochemical modulation of reflected light and luminescence is demonstrated through two examples of fluorophores: one switching…

Photoswitchable Arene Ruthenium Complexes Containing o-Sulfonamide Azobenzene Ligands

A series of arene ruthenium complexes containing ortho-sulfonamide azobenzene ligands were synthesized and found to exhibit uncommon coordination pattern with exocyclic N=N bond. Upon irradiation, these complexes cleanly undergo (E)→(Z)…
