Adsorption of cyanine dye DiI in a nanopous SiO₂ matrix has been studied. It was shown that the increase of the dye concentration in the SiO₂ matrix provokes the appearance of an additional red-shifted band of excimer nature in the dye fluorescence spectrum without any changes in the absorption one....
