Photonic properties and applications of multi-functional organo- lanthanide complexes: Recent advances

Lanthanides (Ln(III)) based compounds as light-emitting materials have emerged as successful agents in high-performance defense and lighting systems, magnets, bio-markers, and circuitry. Therefore, they have recently gained much attention as energy-saving and cost-effective luminescent materials and their applications in analyte detection. The present review summarizes powerful features and recent developments of organo-lanthanide complexes in lighting applications with a particular focus on visible light emitters, including Eu(III), Tb(III), Sm(III), and Dy(III) ions. In addition, this review discusses the most relevant aspects of photosensitization, such as the structure, property, functionalization of primary and secondary ligands, and molecular geometry. In addition, coordination sites of organo-lanthanide complexes and their applications collectively contribute to the improved performance of innovative luminescent materials. Finally, the current challenges and key recommendations for advancing organolanthanides in material science are provided.(c) 2023 Chinese Society of Rare Earths. Published by Elsevier B.V.
