Applicability in Dosimetry of Thermoluminescent Li2B407 Doped with Cu or Eu Impurities

Thermoluminescence properties of lithium magnesium borate glasses system doped with dysprosium oxide

“…In the past two decades, rare earth (RE) ion-doped borate materials have been intensively explored for use in dosimeters (1,(4)(5)(6)(7)(8)(9)(10). Since its inception, this RE doped borate material exhibiting superior TL response, close tissue equivalent and excellent sensitivity have received much attention (11).…”

X-ray luminescence and spectroscopic characteristics of Er3+ ions in a glassy lithium tetraborate matrix

“…Therefore, the development of these materials for radiative monitoring is very important and urgent. Extensive studies of wide-gap insulator Li 2 B 4 O 7 in different (in particular, activated) phase states [1][2][3][4][5][6][7][8] have shown the absence of unified opinion on the nature of radiative centers even for the most widespread phosphor LTB, activated with copper and silver.…”

“…It is known [2,3,5,9,10] that the type of activator in a lithium tetraborate matrix affects significantly its luminescence characteristics and the potential of their practical application. The luminescence properties are related to the energy structure of the pseudoband gap of glassy Li 2 B 4 O 7 , which has some features in the case of wide-gap insulators [5,11,12].…”

“…The study of REEactivated glassy Li 2 B 4 O 7 is of particular interest, because lanthanide oxides are the most favorable objects for doping. Indeed, their incorporation into glassy LTB does not change the matrix structure significantly, which leads in the long run to a considerable increase in the luminescence intensity [3,9,11,12,18]. From the practical point of view, it is important to reveal the nature of luminescence centers; perform a detailed analysis of the structure of their energy levels; and investigate different energy interactions between luminescence centers, which lead to complex processes of excitation energy transfer in glassy LTB activated by Er 2 O 3 .…”

Synthesis and characterization of thermoluminescent Li2B4O7 nanophosphor

“…Thermoluminescent materials exhibit a glow curve with one or more peaks when the trapped charge carriers are released [12]. The dopant plays a significant role in controlling TL properties of lithium borate [13][14][15]. Copper is known to be one of the most efficient luminescence activators.…”
