Description
Summary:A description of the preparation of zirconium oxide (ZrO 2 ) polycrystalline powder by the sol-gel method is presented. To prepare ZrO 2 powder to be used as a thermoluminescent (TL) phosphor in dosimetric application, it is necessary to analyze some structural properties before, such as it's crystallinity. In this work, the property was verified using X-ray diffraction. ZrO 2 polycrystalline powder obtained was subjected to thermal treatment by heating up to 1000 °C. Both the absorption spectrum and the emission spectrum were also studied. The TL glow curve of ZrO 2 powder exhibited a peak when it was exposed to a radiation field. Results of analyzing optical properties and the preliminary results of studying the TL in ZrO 2 , indicate that the latter is a good candidate to be used as a TL dosimeter in radiation ionizing and UV-radiation fields.
