Continuous wavelength and linear modulation optically stimulated luminescence characteristics of beta-irradiated ZrO2

The Continuous Wavelength Optically Stimulated Luminescence (CW-OSL) and Linear Modulation Optically Stimulated Luminescence (LM-OSL) of ZrO2 after irradiation with beta particles were studied. A typical OSL decay of light intensity showed a dependence on illumination time. The LM-OSL curve showed a maximum approximately at 41 s of illumination time. The LM-OSL curve of ZrO2 showed an initial peak followed by a long tail one. The OSL signal showed more than one component. Plotted data as a function of absorbed dose showed linear behavior from 10 to 200 Gy from 90Sr/90Y beta source. esent work summarizes the experimental results obtained for the OSL characteristics of ZrO2 after beta irradiation in order to use it as a beta particles detector. A comparison between CW-OSL and LM–OSL characteristics are also presented.
