Raman spectra of glassy lithium tetraborate activated with different concentration of terbium oxide are investigated. Most of the observed structure in the Raman spectra of Li2В4О7:Tb2О3 glass is caused by mixed vibrations of complex boron–oxyge

This paper examines the effect of doping level on the X-ray luminescence of TbO2-doped polycrystalline lithium tetraborate. It is shown that, when interpreting such spectra, it is convenient to proceed from the terms of free activator and constituent

It has been demonstrated on the basis of absorption spectra measurements that the activation of glassy lithium tetraborate by terbium results in the formation of band of localized electronic states in the pseudo-band gap, which correspond to the ener

Li2B4O7 (LTB) single crystals are grown from stoichiometric and B2O3-enriched (1.6 and 2.4 mol %) melts. At large B2O3 excesses, the thermoluminescence intensity in the crystals is markedly higher, attesting to an increased density of structural defe

The copper-doped lithium tetraborate Li2B4O7 (LBO) is one of the promising materials for the thermoluminescent dosimetry since it possesses the best tissue-equivalence among known non-organic materials used in the dosimetry. In addition, this materia
