Abstract

This study aimed at investigating the influence of Gamma-irradiation 60Co on CoSe/Ag nanostructures material deposited on a transparent conducting substrate via electrochemical deposition technique. The cationic, anionic, and dopant precursors used were respectively 0.01 mol of cobalt (II) acetate tetrahydrate (Co(NO3)2.6H2O), 0.01 mol of selenium (IV) oxide (SeO2), and 0.02 mol of silver nitrate (AgNO3).  The structural, optical, and morphological properties of the deposited films were respectively evaluated using X-ray diffraction (XRD) analysis, UV-visible spectrophotometry, and scanning electron microscopy (SEM). The cobalt selenide/silver films exhibited cubic polycrystalline structure for both unirradiated film at 0Gy and irradiated films of CoSe/Ag material at (200Gy -500Gy) with low bandgap energies and high absorbance values. The surface morphology of the films revealed clustered nanobubbles with no evidence of pinholes. The deposited CoSe/Ag films find potential application in photovoltaic and solar cells.
