Specific nonlinearity concentration and nonmonotonous temperature dependances were experimentally determined for parameters of fluorescence and absorption spectra adsorbed dyes molecules. Those dependances considerably differ from the ones for dyes solutions. Revealed regularities were explained by significant heterogenity intermolecular environment, weak vibrational energy exchange between dye molecules and its local environment and appearance of fractal clusters of adsorbed molecules.
