Abstract

Abstract: C60 /Ag/Au multilayer thin films are synthesized on glass substrate by thermal co-deposition method followed by ion irradiation by high energy ion beam of 120 MeV Au ions using Pelletron accelerator. The effect of ion irradiation by 120 MeV Au ions on the optical and structural properties of the synthesized multilayer thin film samples at different fluences ranging from 6 × 10 12 to 3 × 10 13 ion/cm 2 is investigated. By UV–visible spectroscopy, optical studies of pristine and Au ion irradiated samples are examined. Surface Plasmon Resonance (SPR) peaks of Au and Ag nanoparticles are obtained at wavelength ∼687 nm and ∼628 nm, respectively after irradiation at a fluence of 3 × 10 13 ions/cm 2 . Atomic force microscopy was performed to analyze the surface morphology after irradiation. Due to ion irradiation, overall roughness estimated to be increased with increasing fluence. TEM revealed the growth of metal nanoparticles in size due to agglomeration after irradiation. I–V measurements are preformed to study the electrical properties after irradiation with 120 MeV Au ion.
