Abstract |
|
|
| CdSe films were prepared using the chemical bath deposition method on glass bases and at temperatures of 50°C and 70°C, PH = 9, the CdSe films were exposed to neutron irradiation from the (Am241 – Be10) source with a flux of 3 × 105 n/cm2.s and energy 5.71MeV for a period of irradiation for a 7 days, the optical properties of irradiation were studied using UV - V spectrophotometer, and from the following measurements, XRD, FESEM, EDX, the shape and structure of the prepared films were determined. It was found that there is an effect of neutron irradiation on the optical and structural properties of CdSe films where it was found that there is a transform in the structure of films at a temperature of 70°C from the Cubic structure to hexagonal, and the energy gap increases after irradiation and the absorption coefficient (α) increases with irradiation due to an increase in the energy gap, and the particle size also increases with irradiation, while the relative density decreases with irradiation. The surface shape of the films is significantly affected when the films are irradiated with neutrons. |
