We have performed a comparative study on scintillation and dosimetric properties of monocrystalline and polycrystalline Li2B4O7 samples. The scintillation light yield of the monocrystalline Li2B4O7 sample was higher than that of the polycrystalline Li2B4O7 sample. In contrast, the thermoluminescence intensity of the polycrystalline Li2B4O7 sample was higher than that of the monocrystalline Li2B4O7 sample. These results can be explained by the difference in trap concentration between the monocrystalline and polycrystalline Li2B4O7 samples. It has been assumed that the monocrystalline Li2B4O7 sample shows a higher scintillation light yield owing to its lower trap concentration and the polycrystalline Li2B4O7 sample shows a higher thermoluminescence intensity owing to its higher trap concentration.Corresponding author: Noriaki Kawaguchi
