Herein we report the red-emitting nanocomposites via the adsorption of 2-thenoyltrifluoroacetone on the Eu3+-containing Laponite that was obtained by substituting the positive Na+ ions with Eu3+ via an ion exchange procedure. The in-situ formation of luminescent Eu3+ complexes is confirmed by Fourier Transform Infrared spectra and luminescent data. X-ray diffraction patterns suggest that at least partial complexes are intercalated within the interlayers of the Laponite. Furthermore, we observed that the solvent used in the ion exchange step shows pronounced influence on the luminescent behaviour of the final nanocomposites. In addition, the luminescent nanocomposite displays high photo- and thermo-stability.
