Abstract :

Bayfol DPF 5023 is a class of polymeric solid state nuclear track detector which has many applications in various radiation detectionfields. It is a Makrofol polycarbonate/polyester blend.Samples fromBayfol DPF 5023 film have been irradiated with different fluences (1´10¹¹– 1´10¹⁴ p/cm²) of 1 MeV protons at the University of Surrey Ion Beam Center, UK.The resultant effect of proton irradiation on the structural and optical properties of the Bayfol samples has been investigated using X–ray diffraction XRD, Fourier Transform Infrared FTIR and UV spectroscopy. The results indicate that theproton irradiation up to 10¹⁴p/cm²reduces the optical energy gap that could be attributed to the increase in structural disorder of the irradiated samples. This could correlated to the results obtained from XRD and FTIR measurements.Further, the color intensity DE, which is the color difference between the non irradiated sample and those irradiated with different proton fluences, was decreased with increasing the proton fluence, convoyed by an increase in the red and yellow color components.
