Résumé

The dye coumarin 343 (C343) adsorbed on the surface of ZrO2 nanoparticles in aq. solns. was used to study the solvation dynamics close to these surfaces. The time-resolved Stokes shift was measured by femtosecond frequency-resolved upconversion. The absorption and fluorescence spectra of C343 in water and adsorbed on ZrO2 were analyzed. The solvation functions of C343 in water and adsorbed on ZrO2 nanoparticles were detd. [on SciFinder (R)]
