Abstract
This research paper focused on the thermoluminescent (TL) studies of prepared nanomaterials exposed to gamma radiation. The fabricated nanopowder were pure, and silver (Ag) doped aluminum oxide (Al2O3) were produced utilizing the hydrothermal method. The silver dopant was incorporated into the Al2O3 at three different concentrations (0%, 5%, and 10%). The structure and morphological characteristics of nanoparticles were studied using various tools. First, UV–visible spectroscopy confirmed the doping of Ag and determined the optical bandgap. Field emission scanning electron microscopy, transition electron microscopy, and thermogravimetric analysis (FE-SEM, TEM, and TGA) respectively were used successfully to analyze morphology structure and thermal properties of pure and doped fabricated nanopowder. The crystal structure of the products was examined by the x-ray diffraction (XRD) technique and the average crystal size was found 10.6 nm. The dosimetric study of gamma radiation was successfully applied using a different range of higher irradiation doses. The Al2O3 with varied Ag dopant concentrations demonstrated a high potential as a gamma-ray dosimeter in the near future for a variety of applications including medicine and industry.
