INFLUENCE OF IRRADIATION ON THE OPTICAL BAND GAP OF THE POLYIMIDE - YBA2CU3O6.7 SYSTEM
Abstract
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) decreases with increasing irradiation dose across all studied samples. For pure polyimide, the decrease in Eg is approximately 0.11 eV with increasing dose from 0 to 600 kGy, while the filler-containing composites exhibit a more pronounced decrease, down to 1.2–1.3 eV. The obtained patterns of Eg reduction indicate that, under the influence of gamma-quanta, additional local levels form in the system's forbidden zone due to radiation-induced defects, disruption of the polyimide's conjugated structure, and changes in oxygen non-stoichiometry in YBa2Cu3O6.7 particles.
