It was shown by means of the photobleach method that photostability of
pyrene molecules on the silica surface is independent from concentrat
ion of fluorophor molecules on the surface. On the base of analysis of
kinetics of fluorophor luminescence recovery and solution of two-dime
nsional diffusion equation the diffusion coefficients of pyrene and N,
N-dimethylaniline molecules were estimated.
