of different fluences. The pristine as well as bombarded samples were investigated by UV–
Vis spectroscopy, Fourier transform-infrared analysis (FTIR) and micro-hardness tester. The
variations of wettability and surface free energy were determined by the contact angle
measurements. The obtained results showed that ion beam bombardment induced increase
in the absorption spectra of the UV–Vis with increase of ion fluence as well. The direct and …
