Abstract
The synthesized ZrO2:Cu particles were characterized using X-ray diffraction (XRD) to determine the nanocrystallite size and crystal structure, respectively. The ZrO2:Cu powder with a crystallite size of 30-40 nm has a monoclinic structure and exhibit a thermoluminescent (TL) glow curve with two peaks centered at 130 and 180 {ring operator} C. The TL response of ZrO2:Cu as a function of wavelength exhibited two maxima at 260 and 290 nm. The TL response of ZrO2:Cu as a function of the UV light spectral irradiance was linear in the range from 10 to 2300 mJ / cm2. Fading and reusability of the phosphor were also studied. The results showed that ZrO2:Cu nanopowder has potential to be used as a UV dosimeter in UV radiation monitoring.
