Li-Based Glasses for Neutron Detection — Classic Material Revisited

The background and preparation procedures of Li-based scintillation glasses for neutrons detection are reviewed here. The nuclear-physical modeling was used to justify the composition choice. Technological factors, which strongly influence hands-on glass preparation experience, are considered. Particular attention is paid to understanding the stabilization of activator ions, especially Ce, in 3+ oxidation state. A new approach is proposed, which allows to improve the preparation procedure reliability for glasses based on lithium disilicate.
