Coordination chemistry of the host matrices with dopant luminescent Ln3+ ion and their impact on luminescent properties

Lanthanides (Ln3+) are a unique class of optical materials and are extensively used as building blocks for optoelectronic device architectures due to their outstanding luminescent properties spanning from UV/ Visible to NIR region. This review provides a comprehensive depth description of the variety of host lattices and their coordination chemistry of doped luminescent Ln3+ ions. Crystal structures, morphologies, co-dopant sensitizers to boost the luminescence efficiency, and the formation of the core/shell structure were explored to examine their impact on the efficiency of luminescence performance. Additionally, this review wraps up with recent advances, major future opportunities, and challenges for further development in the field of Photonics-based research. The flourishing development of active Ln3+ nanostructures opens new avenues for their utilization in medical, biotechnological, and applied material sciences in future research directions.
