We have investigated the scintillation properties of Ce-doped Li2O–ZnO–P2O5 glasses. The samples were prepared using a conventional melt-quenching method with low heating temperatures from 900 to 950 °C. All the samples showed halo patterns in their X-ray diffraction (XRD) patterns. In the X-ray-induced scintillation spectra, each sample showed a single emission peak that can be ascribed to luminescence due to the 5d–4f transitions of Ce3+ ions. In the pulse height spectra of the samples, thermal neutron detection peaks were observed. Their light yields were estimated to be approximately 90–180 photons/neutron. Although the Ce-doped Li2O–ZnO–P2O5 glasses show low light yields, they can be regarded as thermal neutron scintillators that can be produced with low heating temperatures.
