Thermoluminescence of Crystallized Glasses Li2B4O7

Thermoluminescence (TL) glow curves and emission spectra were measured for crystallized glasses Li2B4O7 doped with 0.03wt% CuCl2, AgCl, MnCl2 and TbCl3. Two different samples were made: one was a plate of 1mm in thickness and the other was a thin film of 0.1mm bonded to a platinum plate. Both were a...

Summary:Thermoluminescence (TL) glow curves and emission spectra were measured for crystallized glasses Li2B4O7 doped with 0.03wt% CuCl2, AgCl, MnCl2 and TbCl3. Two different samples were made: one was a plate of 1mm in thickness and the other was a thin film of 0.1mm bonded to a platinum plate. Both were annealed at three different temperatures, 620°, 820° and 910°C. TL-glow characters of the samples sticked to platinum plate revealed themselves very sensitive to the annealing temperature. The CuCl2-doped sample annealed at 820°C on platinum plate showed the most intense TL peak at about 160°C, which can be practically used for dosimetry. The X-ray pattern analysis indicates some differences in distribution of microcrystal orientations corresponding to the two different samples. Possible mechanisms for the TL emission were discussed.
