Cerium-doped lithium tetraborate for thermoluminescent dosimetry

Challenges in personal and clinical dosimetry using Li2B4O7 and MgB4O7 as TLD and OSLD

“…Because the expected doses in personal or clinical dosimetry are usually very low, the LDD is an important parameter in determining how close the material is to an ideal dosimeter; a lower LDD value indicates that the material is more likely to be suitable for these types of dosimetry [11,19].…”

“…Lithium tetraborate (Li2B4O7, abbreviated to LBO) is a matrix widely applied in acoustics, electronics, linear and nonlinear optics, and piezoelectric and pyroelectric devices [18,19]. LBO, due to its 9 eV bandgap, has high UV transmittance at wavelengths up to 155 nm [20].…”

“…LBO, due to its 9 eV bandgap, has high UV transmittance at wavelengths up to 155 nm [20]. For dosimetry, dopants such as Ce, Ni, Cu, Ag, P, Mn, and Ag are incorporated into the LBO matrix, with Cu and Ag resulting in a higher luminescent efficiency [8,10,19,[21][22][23][24][25].…”

Unlocking the effect of Li and Ce ions on the thermoluminescence and optically stimulated luminescence signals of the MgB4O7 compound

“…In this case, the incorporation of Li into the host matrix leads to a drastic change in the OSL signal depending on the Li and Ce concentrations. 9–12 The strategy of lithium incorporation has been used to induce positive effects in different phosphors and obtain higher efficient White Light Emitting Diodes (WLEDs). 13 Aliovalent substitution leads to the tuning of the activator site concentration and to the regulation of the local structure of these defects in the host matrix.…”
