| Abstract: | Motivated by the detection of neutrons, europium-doped Li2B4O7 glasses enriched with both lithium and boron elements with high cross-section capture were developed. A highly effective method of realizing the self-reduction of Eu3+ to Eu2+ ions in europium-doped Li2B4O7 glasses prepared by high temperature melt-quenching technology in air was revealed. The self-reduction of Eu3+ to Eu2+ ions can be easily achieved by the partial replacement of B2O3 with BN within 2 mol% concentration. And the effect of partially replacing B2O3 with BN on the optical properties of europium-doped Li2B4O7 glass are systematically studied by transmittance, photoluminescence, and radioluminescence spectra, together with the luminescence decay curves. |
