Enhancement of the Luminescence Properties of Eu (III) Containing Paramagnetic Saponite Clays

In this study, 1,10-phenanthroline molecules were introduced in the interlayer space of a paramagnetic synthetic saponite clay containing both Eu3+ and Gd3+ ions structural positions. Two samples with different loading phenanthroline dye prepared. The resulting hybrid materials possessed improved optical emission properties due to an efficient antenna effect from centers; was demonstrated be higher than metal-to-metal Gd3+-Eu3+ energy transfer previously studied. Insights on relaxometric aqueous solution solids after incorporation groups also obtained through NMR analyses.
