Description
Zinc titanate (ZnTiO3) nanostructures were synthesized by an eco-friendly sol-gel method using an ethanolic plant extract as a reducing and capping agent. The synthesized nanostructures were characterized using X-ray diffraction (XRD) and Raman spectroscopy, which confirmed the formation of the rhombohedral ZnTiO3 phase. Fourier Transform Infrared Spectroscopy (FTIR) confirmed the formation of metal-oxygen bonds, and UV-Vis. absorption spectroscopy indicated strong absorption in the UV region. Dose response studies were carried out under beta irradiation. The initial rise (IR) method and Variable heating rate (VHR) method were used to determine the kinetic parameters of ZnTiO3. Thermoluminescence (TL) studies demonstrated excellent dosimetry properties over the varied doses, good reproducibility (CV = 2.47 %), and stable glow curve characteristics. The initial rise (IR) method and Variable heating rate (VHR) method were used to determine the kinetic parameters of ZnTiO3. The Activation energy found from IR method was
0.72 eV, with VHR yielding E=0.64 eV (R²=0.987), indicating that the two methods are reliable for activation energy determination. The excellent linearity validates the reliability of the kinetic parameters. The results obtained indicate that this material can be used in low-temperature dosimetry applications.
