Growth and luminescent properties of Li2B4O7 single crystal doped with Cu

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 (3d94s → 3d10 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.
