| Abstract: | The structural and
optical modifications of polysulphone polymer under swift heavy ion (SHI)
irradiation have been compared. Polysulphone films were irradiated with 45 MeV Li+3
ions and 120 MeV Ni+9 ions with fluence varying from 3×1010 to
3×1012 ions/cm2. Optical and structural modifications were characterized by UV-visible spectroscpy and X-ray diffraction (XRD) method. It is observed that
optical absorption increases with increasing fluence and the absorption edge
shifts towards the red end of the spectrum. The value of band gap shows a decreasing
trend with increasing ion fluences of both the ions but a sharp decrease in
band gap was observed in case of Ni ion. XRD analysis
shows the decrease in peak intensity with increasing fluence. |
