Journal ArticleDOI
Intrinsic quantum yields and radiative lifetimes of lanthanide tris(dipicolinates)
TL;DR: A modified integration sphere enabling absolute determination of these quantities on small amounts of solid samples or solutions is described, enabling the measurement of the overall and intrinsic quantum yields obtained upon ligand and metal excitation, respectively.
Journal ArticleDOI
Europium and terbium tris(dipicolinates) as secondary standards for quantum yield determination
TL;DR: Aqueous solutions of europium (III) and terbium(III) tris(dipicolinates), around physiological pH are shown to be convenient secondary standards in the determination of quantum yields of lanthanide complexes containing these ions as discussed by the authors.
Journal ArticleDOI
Structural and luminescent properties of micro- and nanosized particles of lanthanide terephthalate coordination polymers.
Carole Daiguebonne,Nicolas Kerbellec,Olivier Guillou,Jean-Claude G. Bünzli,Frédéric Gumy,Laure Catala,Talal Mallah,Nathalie Audebrand,Yves Gérault,Kevin Bernot,Guillaume Calvez +10 more
TL;DR: The isostructurality of the compounds with the previously reported Tb-containing polymer is ascertained on the basis of their X-ray powder diffraction diagrams and the luminescence properties of all the compounds have been recorded and the two most luminescent polymers have been studied in more detail.
Journal ArticleDOI
Luminescent Bimetallic Lanthanide Bioprobes for Cellular Imaging with Excitation in the Visible‐Light Range
Emmanuel Deiters,Bo Song,Anne-Sophie Chauvin,Caroline Vandevyver,Frédéric Gumy,Jean-Claude G. Bünzli +5 more
TL;DR: Examination of data for seven Eu(III) and Tb( III) bimetallic helicates point to shortcomings in the phenomenological rules of thumb between the energy gap DeltaE((3)pipi*-(5)D(J)) and the sensitisation efficiency of the ligands.
Journal ArticleDOI
Conductive Gold Nanoparticle Mirrors at Liquid/Liquid Interfaces
Ping-Ping Fang,Shu Chen,Haiqiang Deng,Micheál D. Scanlon,Frédéric Gumy,Hye Jin Lee,Dmitry Momotenko,Véronique Amstutz,Fernando Cortés-Salazar,Carlos M. Pereira,Zhilin Yang,Hubert H. Girault +11 more
TL;DR: Reflectance and conductance transitions were interpreted as critical junctures corresponding to a surface coverage that exceeded the percolation threshold of the Au NP films at the [heptane + 1,2-dichloroethane]/water interface.
