•Optical properties of 34Li2O–5MgO–10Al2O3–51SiO2 are reported.•Scintillation properties of 34Li2O–5MgO–10Al2O3–51SiO2 are demonstrated.•Developed glass showed fast scintillation decay time.•Scintillation light yield was 700 ph/n.•Energy transfer efficiency from the host to emission center of this glass was high.

Ce-doped 34Li2O–5MgO–10Al2O3–51SiO2 glass was prepared by the conventional melt quenching method and compared with commercially available material, Li-glass (Saint Gobain) on their optical and scintillation properties. They exhibited 80% transmittance at wavelength longer than 350 nm. Photoluminescence (PL) emission peaks of the prepared glass and Li-glass resulted 385 and 420 nm, respectively. Temperature dependences of PL of these materials were examined from 25 to 300 K and they showed different responses. In X-ray induced scintillation spectra, emission peaks were similar to those in PL. Primary scintillation decay time of the prepared glass was largely faster than the conventional Li-glass and resulted few ns. In thermally stimulated luminescence glow curve, the prepared glass showed a deeper trap and it showed better afterglow property. Finally, 252Cf neutron induced light yield was evaluated and the light yield of the prepared glass was around 10% of that of Li-glass.
