Fabrication and properties analysis of lithium borate glass scintillators with transition metal oxides

Nonlinear optics crystals are vital fundamental materials in optoelectronic technology, and also important for other fields, such as information, energy resource, medical application, etc. Lithium borate system has attracted considerable attention because this system contains many important nonlinear optics crystals, such as 2Li₂O-3B₂O₃, L₂O-B₂O₃, Li₂O-2B₂O₃, Li₂-3B₂O₃, etc. This study fabricated a Li₂O-B₂O₃ glass scintillators with TMO (transition metal oxide) activators. The crystal structure of the fabricated Li₂O-B₂O₃ glass scintillators were confirmed, and experiments were conducted to study the absorption curve by density of the added activators, photorefractive effect, band-gap energy, emission spectrum and elemental composition. Also, the purpose of this study is to develop a glass scintillator with improved performance by improving on it through continued researches and experiments. Further researches on light efficiencies of the glass scintillator prepared in this study for neutron irradiation should be performed. In addition, by changing compositions for glass scintillator showing good performance, it will also be carried out to calculate composition ratios for neutron glass scintillators and to prepare ones with best performance.
