Polycarbonate (PC) films were irradiated by 100MeV gold (Au7+) ions and characterized to study changes in its optical, chemical, surface morphology and thermal properties. UV–Visible spectroscopic results revealed the decrease in the optical band gap of PC after ion irradiation due to chain scission mainly at the carbonyl group which is corroborated by Fourier Transform Infrared spectroscopic results...
