Abstract

The kinetics of fluorescence decay of the Bengalese pink dye adsorbed on the surface of wide-porous silica with addition of anthracene is investigated in the case in which the fluorescence decay slows down due to annihilation. The experimental kinetic dependences recorded at temperatures in the interval from 153 to 273 K are examined by methods of multifractal analysis and computer modeling. A comparison of the experimental dependences with the results of computer modeling has demonstrated that changes in the kinetic luminescence characteristics of the system at different matrix temperatures are caused by reorganization of structural elements in the system leading to changes in ordering and fractal dimension of the reagent molecule distribution.
