A special group of luminescence materials are scintillators for thermal neutron detection. Due to the properties of neutrons, a different approach has to be utilized—the high content of atoms with the sufficient absorption cross-section toward neutrons and lower material density are needed. This work pursues a basic study of LiSrBO3 and LiSr4(BO3)3 doped with cerium or europium—materials promising as thermal neutron scintillators. These borates exhibit promising properties such as the high content of lithium and boron, suitable density, and proper environment for luminescent ions. Radioluminescence of these ceramic borates doped with cerium and europium was examined and promising samples were further characterized by photoluminescence spectroscopy and radioluminescence and photoluminescence kinetics measurement. The radioluminescence study of these borates is published for the first time. Cerium-doped borates, in particular, exhibit a very promising response to an X-ray excitation.
