In this study, the effect of high-energy proton irradiation on the optical properties ofpolyacrylonitrile (PAN) films was investigated. PAN thin films spin-coated on a substrate wereirradiated 150 keV proton ions at various fluences. The changes in the chemical structure andoptical properties were investigated by FT-IR and UV-vis spectroscopy. The results of the FT-IRanalysis revealed that the cyclization reaction took place by proton irradiation and the degree ofcyclization increased with an increasing fluence. Based on the UV-vis analysis, the optical bandgap of PAN decreased from 2.84 to 2.52 eV with an increasing fluence due to the formation ofcarbon clusters by proton irradiation. In addition, the number of carbon atoms per carbon clusterand the number of carbon atoms per conjugation length were found to be increased with anincreasing fluence.
