Abstract
A novel series of Cr2O3-Al2O3 nanoparticles containing various molar compositions of Cr2O3 (0–2wt%) were prepared by sol-gel method. An octadecylamine was used as nano-assembling template to prepare novel dosimeter nanoparticles. The crystalline features, morphology, sample composition and the nanostructure of the prepared samples were investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray (EDX) and high resolution transmission electron microscopy (HRTEM). The XRD and HRTEM results reflected the existence of nanoparticles with rod-like structure. It was found that Al2O3 nanoparticles with compositions of 1.5% Cr2O3 exhibited the highest response for gamma rays than all different compositions. This composition displayed a linear gamma dose response in the range from 3.5mGy up to 350Gy. The investigated samples exhibited a difference of the sensitivity for beta rays according to the applied dose ranges. The minimum detectable dose of the prepared samples was evaluated as 27.2µGy. The results showed that no fading was exhibited for the investigated samples by measuring one day after the irradiation process.
