Hybrid multifunctionalized mesostructured stellate silica nanoparticles loaded with β-diketonate Tb³⁺/Eu³⁺ complexes as efficient ratiometric emissive thermometers working in water

Abstract

Despite the great effort brought in recent years on lanthanide based ratiometric luminescent nanothermometers able to provide temperature measurements in water, their design remains challenging. We report on the synthesis...

Luminescent Ln3+-based silsesquioxanes with a β-diketonate antenna ligand: toward the design of efficient temperature sensors

“…This results in a weak interaction concerning Tb-Eu energy transfer between different {Ln 4 } clusters. Thus, the Tb-Eu interaction is restricted to intra-cluster energy transfer, which can lead to highly effective energy transfer rates, as discussed in the literature ( Wang et al, 2014 ; Calado et al, 2023 ; Gálico et al, 2023 ; Pelluau et al, 2023 ).…”
