Lanthanide molecular cluster-aggregates as the next generation of optical materials

Abstract

In this perspective, we provide an overview of the recent achievements in luminescent lanthanide-based molecular cluster-aggregates (MCAs) and illustrate why MCAs can be seen as the next generation of highly...

“…with among other a part dealing with luminescent thermometry (Figure 23). The same leading author proposed in 2023, [268] a review focused on high nuclearity 4 f molecules as tunable luminescent materials for anti‐counterfeiting, luminescent thermometry, and molecular upconversion.…”

Composition Control in Molecular Cluster-Aggregates: A Toolbox for Optical Output Tunability via Energy Transfer Pathways

“…From this perspective, Ln III -based molecular cluster-aggregates (MCAs) have emerged as a suitable platform for luminescence at the nanoscale. − In addition to a large number of emitting centers within a precise crystalline structure, MCAs offer excellent control over uniformity and composition. − On top of that, the careful choice of a ligand moiety ensures, at the same time, core rigidity (which reduces phonon-assisted deactivation routes) and a suitable way to efficiently sensitize Ln III optical centers. The so-called “antenna effect” is essential to account for the low absorption coefficient of Ln III and accomplish high performance.…”

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

“…Note that it may be considered as a“lanthanide molecular cluster” with promising photo-luminescence properties. 52 Its high nuclearity ensures a rigorous co-localization of both luminescent probes (Tb 3+ and Eu 3+ ) in the silica pores and optimized conditions for correlation with local temperature measurement. Additionally, this configuration offers the advantage of controlling the Tb 3+ /Eu 3+ ratio, which is not feasible with the separate use of Eu and Tb mononuclear complexes.…”
