Optical absorption spectra, optical conductivity, refractive index n, extinction coefficient k and photoluminescence in nanocomposite films of poly-N-epoxypropylcarbazole (PEPC) with 0,7; 1,35; 2,5 and 4 wt.% of C60 molecules were studied. Substantial restructuring of these spectra with changing the fullerene C60 content was established not only in the intrinsic absorption, but also within the energy gap. Reducing the energy distance between states S1 and T1 with increasing concentration of C60 molecules was showed, as well as the appearance of additional broad structureless bands with a maximum near 700 nm in the long-wave photoluminescence spectrum. Restructuring of the spectra is associated with electron-conformational changes caused by appearance of the donor-acceptor interaction between components in the films PEPC-C60 due to formation of the complexes with charge transfer (CCT) in them.
