Beschreibungen/Notizen

• Non-irradiated and irradiated ceramics of Li2B4O7:Mn, Li2B4O7:Mn,Be, and Li2B4O7:Mn,Cu were studied using electron paramagnetic resonance and luminescence spectroscopy. The emission of Mn2+ centres is observed in the thermoluminescence spectra of the low-temperature and dosimetric high-temperature glow peaks in irradiated samples. Arguments are given in favour of hole mobility being responsible for the dosimetric thermoluminescence peak at 490 K in Li2B4O7:Mn. The co-doping of Li2B4O7:Mn with Cu+ is shown to increase the sensitivity of the material to ionizing radiation. ► Doped Li2B4O7 ceramics were studied by EPR and optical spectroscopy. ► In Li2B4O7:Mn ceramics Mn2+ emission is observed for the TSL peaks at 90 and 490 K ► We propose the release of holes to be responsible for the dosimetric peak at 490 K.
