Abstract: 
High light yield scintillation materials on the base of lanthanide ions were demonstrated to be a multipurpose scintillation materials. They are widely used to detect gamma-quanta and now become prospective to detect neutrons as well. Neutrons were detected through several distinct low energy gamma-quanta peaks, generated by lanthanide nuclei in the materials under neutrons. Among three crystalline scintillators, namely lutetium oxy-orthosilicate, lanthanum bromide and gadolinium-aluminum-gallium garnet, the Gd3Al2Ga3O12:Ce (GAGG) scintillator showed the best performance and sensitivity due to the low internal background radioactivity and good cross section of neutron capture by natural mixture of the matrix host-creating Gd ions. The material fits the requirements for neutron detector properties - high Gd content and high scintillation light yield, stopping power and reasonable energy resolution for gamma-quanta. These findings create prospects to construct compact multipurpose detectors for space and other application.
