Abstract

The radiative characteristics of sol-gel glasses doped with quinine sulphate are investigated to study the effects of the porous matrix upon the absorption and fluorescence spectra. The broadening of the spectra is explained in terms of an inhomogeneous distribution of the adsorbed molecules into the porous glass. This inhomogencous distribution is produced by the attachment of the molecules to the substrate in a non-planar fashion or on distorted sites, for this reason each emitting center relaxes with its own characteristics.
