Title: Polar solvation dynamics of H[sub 2]O and D[sub 2]O at the surface of zirconia nanoparticles

Abstract

Time-resolved fluorescence-upconversion spectroscopy has been used to study the polar solvation dynamics of H[sub 2]O and D[sub 2]O at the surface of zirconia (ZrO[sub 2]) nanoparticles. While an isotope effect is observed for the solvation dynamics of bulk D[sub 2]O, there is no isotope effect on the interfacial solvation dynamics. The interfacial solvation dynamics are the same for H[sub 2]O and D[sub 2]O and are faster than the bulk solutions. The bulk isotope effect is due to stronger hydrogen bonding in D[sub 2]O compared to H[sub 2]O, slowing the reorientation of the excited-state dipoles in the bulk D[sub 2]O. The lack of isotope effect for the interfacial dynamics is explained in terms of the solvent interacting with the ZrO[sub 2] surface.
