Dynamics of molecular exchange-resonance photoprocesses on the surface of chemically modified silica

The photoprocesses with organic lumenophors adsorbed on the surface of broad-porous silica chemically modified by n- alkyl hydrocarbons after laser photoexcitation are considered. The results obtained are interpreted in terms of the exchange-resonance processes of triplet-triplet energy transfer acceleration diffusion model along with homo- and hetero-triplet-triplet annihilation of the interacting molecules.
