Effect of varying lanthanide local coordination sphere on luminescence properties illustrated by selected inorganic and organic rare earth complexes synthesized in sol-gel host glasses

► In this study, we prepared a series of Eu-complexes (organic and inorganic) via the sol-gel glass. ► The sol-gel glass serves as an inert matrix to host the complexes. ► The ultimate goal is to incorporate these complexes in this inert optically transparent material to maximize emission from these complexes. ► Spectrofluorometry was used to diagnose emission.
