The effect of Ti and V dopants on the thermoluminescence properties of lithium borate glass

الملخص EN

The influence of dopants, Ti and V, on the thermoluminescence (TL) properties of lithium borate glass (LB) is investigated in this study.

The samples were exposed to different γ-ray doses in the range 1–10 Gy and their thermoluminescence (TL) was recorded in the temperature range 323 - 673 °K.

The optimum concentration for enhancing the (LB) was 0.6mol% and 0.2mol % of TiO2 and V2O5 respectively.

The glow curves of the two products have three peaks at 628, 648 and 654ᵒK for LB:Ti and 627, 648 and 660ᵒK for LB:V.

The TL response of the principal peak exhibited a linear increase with the increases of γ-dose.

The comparison of TL response of the studied glasses with that of LiF:Mg,Ti (TLD-100) indicated an improvement in the dose response in terms of linearity even though with lower sensitivity for the measurement of γ-doses.

The kinetic parameters were estimated using the peak fit deconvolution technique.

From the experimental data it can be shown that the LB:Ti and LB:V are suitable for radiation measurement.
