Researchers in China have created a new family of nano-wheel-like metallic compounds, specifically lanthanide-based nano-clusters, which possess unique properties such as fluorescence and varying types of magnetism. These advancements could significantly enhance applications in next-generation technologies, including advanced sensors. Despite the established nature of wheels, the synthesis of these novel nano-wheels addresses the need for materials that exhibit controlled properties.
Led by Professor Yan-Zhen Zheng from Xi’an Jiaotong University, the team focused on polymetallic complexes utilizing rare earth elements like europium, terbium, and gadolinium. These lanthanide-based compounds have attracted attention for their intriguing magnetic and luminescent behaviors. Researchers employed hydrolysis in the presence of a stabilizing ligand, tricine, to create three distinct lanthanide nano-clusters characterized by their stable, wheel-like structures. Each cluster demonstrated different properties: the europium-based cluster emitted red fluorescence, the terbium-based cluster emitted green fluorescence, and the gadolinium-based cluster showed potential for magnetic cooling applications.
Ongoing investigations aim to explore further synthesis and applications of these promising nanomaterials. This research contributes valuable insights into polymetallic complexes and their potential in various fields.
