The samples were irradiated by 5 MeV protons with fluence of 1.0 x 1013 ions/cm2, 5.0 x
1013 ions/cm2, 1.0 x 1014 ions/cm2, 5.0 x 1014 ions/cm2 and 1.0 x 1015 ions/cm2 . A nonirradiated
reference sample as well as irradiated samples were subjected to X-ray
diffraction (XRD), Field effect scanning electron microscopy (FESEM,and Fourier
transform infrared (FTIR) spectroscopy. The XRD study indicates the gradual increase in
the intensity of the X-ray scattering with increasing proton ion fluence. The crystallinity,
micro strain, dislocation density and distortion parameters were found to be increasing
with fluence whereas the crystalline size(L) decreases to nano-sized particles at the highe
proton fluences as compared to the reference. The generation of nanoparticles on the
surface at the highest proton fluence have been further confirmed by FESEM
morphology. It is believed that generation of nano particles on surface with Proton
irradiation might be due to chain scission process.FTIR spectra also show changes in
intensity of the typical bands after irradiation The results obtained from the present
investigation can be used successfully in heavy ion dosimetry using well known
techniques.
This study investigates the effect on structural, thermal and electrical properties of PM-355 as a function of different Proton fluence values having energy of 5 MeV. The reference and irradiated…
