The study of the effect of fullerenol (С60(ОН)44) dopant of different concentrations on the optical properties of polyvinyl alcohol (PVA) films has been presented. The addition of even a small concentration of fullerenol was found to lead to significant light absorption in the UV spectral range. As the concentration of fullerenol increased from 1 to 10 wt.%, the light transmission edge of the PVA : С60(ОН)44 composite films shifted from 230 to 440 nm. The dependences of the extinction coefficient (EC) on the fullerenol concentration in the films were calculated for several wavelengths; these curves decreased with С60(ОН)44 concentration increasing from 1 to 3 wt.%, but then EC values stopped decreasing. The light absorption in the studied samples was shown to cause by the fullerenol molecules’ excitation during indirect HOMO → LUMO transitions. The Eg value estimated from their spectra, was 2.2±0.3 eV and depended little on the fullerenol concentration.
