Analysis of absorption, fluorescence, and time-resolved emission spectra of rhodamine 6G in hybrid porous nanolayers at high dye concentration allowed identification of two fluorescent species: monomers and fluorescent aggregates. The method of determination of mean local concentration of aggregates in matrices is proposed based on the energy transfer process between monomers and fluorescent aggregates. Evaluation of aggregate mean local concentration was carried out by comparing the results of Monte Carlo simulation of forward and reverse nonradiative energy transfer between monomers and aggregates with experimental data of fluorescence decay in which monomer and aggregate concentration were treated as best fit parameters.
