摘要：

The authors have primarily succeeded in the study of the technology for growing single crystal Li2B4O7 doped with Cu ions by Bridgman technique. The TL-3D spectra show peaks at around 375 nm (3d(9)4s -> 3d(10) radiative excitation transition). This success opened up an opportunity in the radiotherapy to manufacture scintillators for neutron detection. The kinetic parameters of thermal stimulation luminescence were investigated by the three point method.
