Fabrication and investigation of thermoluminescence properties of Zn2SiO4/SiO2 nanophosphor with manganese impurity

Abstract

Considering the widespread use of radioactive materials and ionizing rays in most fields,such as agriculture, medicine, industry, and energy supply, The presence of a dosimeter is necessary to measure the dose of these rays to reduce their damage. The present study involves the synthesis of Zn2SiO4/SiO2:Mn nanophosphors utilizing ZnC4H6O4 powder, NaOH, and SiO2, followed by heating at 950 ◦C to develop a thermoluminescence dosimeter for potential use in various applications. Structure and morphology of the Zn2SiO4/SiO2:Mn nanophosphor were studied utilizing techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). The thermoluminescence (TL) glow curves of the Zn2SiO4/SiO2:Mn nanophosphor were meticulously analyzed under controlled laboratory conditions. Analysis results revealed that the nanophosphor has a remarkable sensitivity towards low doses of ultraviolet rays. The study demonstrated the effectiveness of Zn2SiO4/SiO2:Mn nanophosphor in detecting and measuring ultraviolet radiation.
