Structural and thermoluminescence properties of magnesium oxide by exposed to beta radiation

Abstract

In this research, magnesium oxide nanoparticles were produced through the chemical spray pyrolysis technique by using magnesium chloride and deionized water at room temperature. Structural characterization of magnesium oxide was carried out by x-ray diffraction system, the pattern confirmed that the prepared magnesium oxide sample has a pure MgO phase with (2 0 0) orientation. Scanning electron microscopy images (SEM) showed that the surface was covered by spherical and irregular shapes in different sizes on the nanoscale ranging between 50 nm and 100 nm. UV–Vis spectroscopy system was used to estimate the band gap energy; it was equal to 3.7 eV. In addition, we investigated the thermoluminescence and dosimetric characterization of magnesium oxide by studying the TL glow curve intensity. The results exhibited that the intensity of TL is increased with increasing of absorbed dose as a function of the temperature. According to the obtained results, MgO is a promising material as a TLD device.
