About this Research Topic
Photoluminescence of chemical materials is a classic approach of energy conversion which can make wavelengths of absorbed photons larger or smaller. Different from these ones derived from organics or quantum dots, lanthanide photoluminescence is extremely unique and valuable because of its sharp emission bands, long luminescence lifetimes, high quantum yields and large Stokes shifts as well as prominent color purity. As a result, photoluminescent lanthanide materials have been widely used in the lighting, displays, telecommunications, anti-counterfeiting, chemosensing, as well as biological applications, etc. All the time researchers pay much attention to the coordination-assembled lanthanide materials which are constructed by coordination interactions using particular lanthanide ions and well-designed organic ligands. One critical reason is that wavelength and intensity of lanthanide luminescences can be easily tuned in these assemblies by various ways, for instance the emitters, chromophores and architectures.
Luminescence of coordination-assembled lanthanide materials is closely related to many energy migration processes in luminescence sensitization by organic ligands which are highly affected by non-radiative deactivation processes. Presently, researchers are particularly focused on coordination microenvironment for better protection and more efficient energy transfer, heteropolynuclear structure with multi-emission luminescence, molecule materials with the upconversion sensitization process, energy transfer mechanism in composites, and so on. All of these new trends will make relative photonic areas flourish. It is also emphasized that the key issues are the structure design, material synthesis and relative characterization for frontier fundamental science and practical applications. This research topic is eager for works on a variety of lanthanide complexes, MOFs, clusters, hybrids, composites and molecular upconversion systems. We envisage that the collection of multidisciplinary manuscripts will attract increased research interest of lanthanide luminescence to further promote the development of correlative fields.
We welcome researchers to submit original research articles, perspectives and reviews related to novel coordination-assembled photoluminescent lanthanide materials and their potential applications. In this research topic, specific themes will include, but not limited to:
• Precise synthesis and functional devices of luminescent lanthanide complexes;
• Luminescent lanthanide organic frameworks (Ln-MOFs) and devices for sensing;
• Tunability in structure and luminescence of nanosized lanthanide molecular clusters and their aggregates;
• Lanthanide-polymer supramolecular self-assembly materials and intelligent devices;
• Coordination mechanics and charge transfers in organic molecule-lanthanide nanoparticle composites;
• Molecular upconversion systems and miniaturization of upconversion devices.
