  • 摘要:Abstract The present paper reports the thermoluminescence (TL) properties of combustion synthesized Ti doped ZrO2 nanophosphors the effect of annealing on \{TL\} glow curve was also studied. The structural characterizations were done by X-ray diffraction technique (XRD), composition by Fourier transformation infrared spectroscopy and surface morphology was determined by field emission gun scanning electron microscopy (FEGSEM) technique. The prepared phosphor annealed at 600 °C, 700 °C, 800 °C and 900 °C and its thermoluminescence glow curve were recorded. The heating rate effect, the thermal quenching as well as the annealing temperature of the material were optimized for the \{TL\} glow curve of the sample. The \{TL\} glow curves for different UV, gamma doses and for Ti concentration were studied. The \{TL\} glow curve of prepared samples have glow peak at 173 °C. The kinetic parameters was calculated by Computerized glow curve convolution technique (CGCD) technique. Fading and reusability studies of the nanophosphor further confirmed the phosphor's suitability for radiation dosimetry. The main conclusion is that Solution Combustion Synthesis is one of the appropriate method for synthesis of Ti doped ZrO2 nanophosphors, which is suitable for temperature sensing applications, the post-synthesis annealing regime being one of the parameters that can affect the intensity and other parameters.
