چکیده انگلیسی
The aim of the current study was to synthesize polyvinyl alcohol Cuprous Oxide composite films (PVA/Cu2O) for radiation detection depending on optical changes. The method adapted from solving of 5% PVA in hot (80â¯Â°C) stirred water and after cooling to ambient temperature a 0.5â¯g of Cu2O dissolved and stirred for 2â¯h. The films were made by casting in petri dishes contained 20 ml/each. The pealed films were enveloped after drying and receiving radiation doses of 1, 2, 4, 6 ⦠12â¯Gy. The analysis revealed a gradient change in color of films from light pink to dark brown with absorption peaks at 215 and 415â¯nm through entire doses which were increase as dose increment. The optical density of films increases linearly and significantly (R2â¯=â¯0.9) as the dose increases from 0.06 (arb. unit) at 1â¯Gy to 0.4 (a u) at 12â¯Gy with sensitivity at 0.06â¯mGy. The energy band gap of the film decreased as the radiation dose increases from 3â¯Ãâ¯10â12 to 2â¯Ãâ¯10â12â¯eV. Conclusively; the feasibility of utilizing PVA/Cu2O composite films as radiation detector and personal dosimeter would be applicable in rural sectors and low economic countries.
