In recent years, the use of nanosensors for the development of research in nuclear technology has had a special place. Due to the high accuracy in absorbing, detecting and measuring gamma rays, these devices are noticed well. In this study, the development of composite gamma nanosensors of cadmium telluride quantum dots using gadolinium ion paramagnetic ions was considered. The nanocomposite was synthesized using a polyvinyl acetate matrix containing characterized cadmium telluride quantum dots doped with gadolinium. The nano-sensor was then fabricated using gold-plated copper electrodes. The characteristics of nanosensors against gamma ray were investigated and compared with other nanosensors without gadolinium ion. The results showed that nanosensors with gadolinium ion in the structure of quantum dots have better and more accurate performance as gamma ray probes.
