The rational engineering of molecules is a powerful chemistry tool pivotal importance in the fields molecular magnetism and luminescence. Hence, systems that can be modulated via composition control are expected to present extra versatility regarding tunability their properties. This case with cluster aggregates (MCAs), high nuclearity compounds. Herein, we demonstrate how union both strategies, namely, engineering, employed enhance upconversion MCAs. was achieved by doping

The conventional energy transfer pathway in organic lanthanide complexes is purported to be from the excited singlet state of chromophore triplet and subsequently directly emitting trivalent ion. In this work, we found that occurs nearest level, instead decay rate for different ions follows an gap law level receiving Three categories were synthesized inspected using techniques, demonstrating universality our findings. This work renews insights findings, highlighting importance between optimization light harvesting. rationale ligand design chromophores should reconsidered, leading various applications with enhanced quantum yield brightness.

Here, Yb-based Eosin Y lakes (EOS-Yb) have been encapsulated in organic nanoparticles (NPs) by microemulsion radical polymerization of methacrylate-based copolymers. These photoactive EOS-Yb NPs emit the visible and near infrared (NIR) upon excitation at 530 nm can also display NIR-to-visible upconversion emission 980 nm.
