The effect of gamma irradiation on the optical band gap of polyimide film and its composites with a filler of finely dispersed powder of high-temperature superconductor (HTSC) YBa2Cu3O6.7 with concentrations of 0.05% by weight; 0.1% by weight; 0.5% by weight was studied. Optical properties were studied in the spectral range of 190-1100 nm using a Shimadzu UV-3600 spectrophotometer. Based on optical absorption spectra and optical band gap calculations for the composite system, we find that the optical band gap (Eg)...
