Abstract

Non-irradiated and irradiated ceramics of Li2B4O 7:Mn, Li2B4O7:Mn,Be, and Li 2B4O7:Mn,Cu were studied using electron paramagnetic resonance and luminescence spectroscopy. The emission of Mn 2+ 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 Li2B 4O7:Mn. The co-doping of Li2B4O 7:Mn with Cu+ is shown to increase the sensitivity of the material to ionizing radiation.
