Thin films of lead sulfide (PbS) were prepared on glass substrates using the successive ionic layer adsorption and
reaction technique. To investigate the gamma-induced properties, the deposited thin films were sequentially
exposed to 60Co gamma rays at doses varying from 0 to 75 kGy. X-ray diffraction analysis of the pristine and
irradiated samples showed that the crystallinity of the PbS thin films increased with the gamma dose. Fieldemission
scanning electron microscopy revealed that the PbS particle size increased with the gamma dose up to
25 kGy, and then decreased. Defect peaks at 805.54 and 833.89 nm were found in the photoluminescence
spectra of the pristine samples that were annihilated owing to the gamma exposure. Impedance spectroscopy
indicated that the radiation effect increased the grain resistance as the dose level was increased. The noticeable
changes induced in the structural, optical, and electrical properties of the PbS thin films clearly introduce the
possibility of using them in gamma dosimetry applicat
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…
The samples were irradiated by 5 MeV protons with fluence of 1.0 x 1013 ions/cm2, 5.0 x
