Abstract
Excitons in thin films are analyzed using Green's function method within the framework of Tyablikov's version of random phase approximation. The spectra of surface and bulk excitons were determined and the distribution of exciton concentrations over film layers was evaluated. It was shown that high surface concentrations could be achieved by decreasing of the dipole-dipole interaction of the molecules in surface layers.
