Kucherenko М.G., Chmereva T.M. PULSE FORM OF DYES CROSS-ANNIHILATION DELAYED FLUORESCENCE IN OXYGEN INCLUDED NANOPOURES MATERIALSThe mathematical model of the kinetics of cross-annihilation reactions of electronic excitations of molecules of oxygen and organic luminophors which proceeds in spherical nanoporous is developed. The model considers the lateral diffusion of the oxygen in the surface layer and it desorption in internal area of a cell. The desorption influence on the signal intensity of the delayed fluorescence of luminophor molecules is shown.Key words: cross-annihilation reaction, lateral diffusion, nanoporous, delayed fluorescence, surface potential.
