Abstract: The Rhodamine 6G (R6G) dye sample synthesized by thermal evaporation method is irradiated by 120 MeV Ag+9 ions at different fluences from 1 × 1011 ion/cm2 to 3 × 1012 ion/cm2. These samples are characterized by X-ray diffraction (XRD), ultraviolet–visible (UV–Vis) absorption spectroscopy and photo-conductivity measurements. In XRD, it is observed that amorphous nature of dye films increases with fluence and hence aggregates of dye molecules spread homogeneously on the substrate after irradiation. The absorption spectroscopy and photoconductivity results show maximum absorption and minimum photoresistivity at lowest fluence. The properties of the dye films such as increase in amorphous nature, increase in absorption peak area and marginal increase in photoconductivity are favorable for Dye-sensitize solar cell (DSSC) applications.
