Spectroscopic properties of Rhodamine B entrapped in hybrid porous nanolayers at high dye concentration
Abstract
The preparation procedure and characterization of Rhodamine B entrapped in zirconia, silica and mixed silica–zirconia nanolayers is described. The nanolayers were produced by the sol–gel spin-coating technique. The pronounced effect of the dye concentration on the absorption and fluorescence spectra as well as on time-resolved fluorescence spectra was found. The results show that the aggregation of Rhodamine B is stronger in silica based matrices compared to zirconia nanolayers. Time-resolved emission spectra at highest Rhodamine B concentration show that the dye aggregates are fluorescent.
