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…

Interaction mechanisms of antibiotic sulfamethoxazole with various graphene-based materials and multiwall carbon nanotubes and the effect of humic acid in water

We studied the interaction mechanisms between carbonaceous nanomaterials (CNMs) and sulfamethoxazole (SMX) to elucidate their adsorption behaviors. Three graphene-based materials, reduced graphene oxide (rGO), graphene oxide (GO), and graphene…

Modulation of Eu(III) and Yb(III) Luminescence Using a DTE Photochromic Ligand

In this work, we show that a dithienylethene (DTE) modified dipicolinic amide ligand can be a versatile tool to modulate Eu(III) and Yb(III) luminescence using light as an external stimulus. The nature of the modulation depends on the lanthanide…
