Thermoluminescence study and characterization of Mn-doped Li2B4O7 exposed to beta radiation
摘要
Lithium tetraborate (Li2B4O7) was synthesized using the precipitation-aided high-temperature solid state technique followed by heating at various sintering temperatures. Then, Li2B4O7 was doped with Mn using several concentrations to find the optimum composition. Manganese-doped lithium tetraborate (Li2B4O7: Mn) was characterized using XRD, SEM, and TL techniques. Li2B4O7: Mn was irradiated using Sr-90 at several irradiation doses to investigate how the material responded to the β radiation. Based on this experiment, the TL dose response is linear for the absorbed dose from 10 to 30 mGy. Such a feature makes this synthesized material a promising material for dosimetry applications.
