Adsorption, Mobility and Organization of Organic Molecules at Clay Surfaces Probed by Photophysics and Photochemistry.
Abstract
This study was initiated to obtain a more characterized colloidal system compared to the clay suspensions (monodisperse, no interparticle exchange, no aggregation of the colloidal particles). In order to facilitate the interpretation of the fluorescence decays of adsorbed molecules. This system is further investigated in more detail. It was however found that also in this system the fluorescence decays of the adsorbed molecules are rather complicated. This phenomena, the complicated fluorescence decay of molecules adsorbed on various surfaces, is very common in literature. A lot of different functions have been used to describe the fluorescence decays of adsorbed molecules. It is indeed possible that a fluorescence decay can be fitted by various different functions. Therefore it seemed appropriate to start a more theoretical study, to find out to what extent it is possible to distinguish between several models. (AW)
