Abstract

This paper reports on the results of an investigation of polymer thin films by the methods of thermally stimulated currents and current-voltage characteristics. It has been found using these methods that, in the band gap of the poly(diphenylene phthalide) films, there are three groups of electron traps with maxima in the density of states at energies of 0.50, 1.06, and 2.40 eV with respect to the bottom of the conduction band. These results correlate well with the data obtained in our investigation of the fluorescence excitation spectra.
