Borehole logging tools and systems that include a scintillator positioned to interact with scattered source neutrons that are received from a target formation. The scintillator emits luminescence in response to interaction with the scattered neutrons. The scintillator includes an aluminofluoride host material (e.g., LiCAF). In a specific embodiment, the aluminofluoride host material is doped with europium. In a further specific embodiment, a processor distinguishes scattered neutrons from gamma rays based upon identifying a peak within an output signal from the scintillator. In yet another specific embodiment, a system includes a first scintillator and a second scintillator. The processor subtracts luminescence generated by the second scintillator from luminescence generated by the first scintillator to identify a neutron response of the first scintillator.
