Bifunctional Paramagnetic and Luminescent Clays Obtained by Incorporation of Gd³⁺and Eu³⁺ Ions in the Saponite Framework. Inorg. Chem. 2021, 60 (14), 10749–10756. https://doi.org/10.1021/acs.inorgchem.1c014550020-16691520-510Xhttp://hdl.handle.net/2183/28553The Supporting Information is available free of charge at https://pubs.acs.org/doi/10.1021/acs.inorgchem.1c01455.[Abstract] A novel bifunctional saponite clay incorporating gadolinium (Gd³⁺) and europium (Eu³⁺) in the inorganic framework was prepared by one-pot hydrothermal synthesis. The material exhibited interesting luminescent and paramagnetic features derived from the co-presence of the lanthanide ions in equivalent structural positions. Relaxometry and photoluminescence spectroscopy shed light on the chemical environment surrounding the metal sites, the emission properties of Eu³⁺, and the dynamics of interactions between Gd³⁺ and the inner-sphere water placed in the saponite gallery. The optical and paramagnetic properties of this solid make it an attractive nanoplatform for bimodal diagnostic applications.engAtribución 4.0 Internacional (CC BY 4.0)https://creativecommons.org/licenses/by/4.0/journal articleopen access
