Makrofol-KG; ion irradiation; UV–visible spectroscopy; X-ray diffraction; Fourier transform infrared spectroscopy; atomic force spectroscopy
In the present study, the effects of swift heavy ion beam irradiation on the structural, chemical and optical properties of Makrofol solid-state nuclear track detector (SSNTD) were investigated. Makrofol-KG ﬁlms of 40 𝜇m thickness were irradiated with oxygen beam (𝑂8+) with ﬂuences ranging between 1010 ion/cm2 and 1012 ion/cm2. Structural, chemical and optical properties were investigated using X-ray diffraction, FTIR spectroscopy and UV–visible spectroscopy methods. It is observed that the direct and indirect band gaps of Makrofol-KG decrease after the irradiation. The XRD study shows that the crystalline size in the ﬁlms decreases at higher ﬂuences. The intensity plots of FTIR measurements indicate the degradation of Makrofol at higher ﬂuences. Roughness of the surface increases at higher ﬂuence.
