Thermoluminescence Characteristics of SrB6 O10:Tb

Keywords： thermoluminescence

SrB6O10:Tb phosphor was synthesized by high-temperature solid state reaction. The influences of Ce or Li as a co-dopant, Tb concentration and irradiation dose exposure on TL of SrB6O10:Tb were investigated. Results show that Ce or Li as a co-dopant can not improve the sensitivity of SrB6O10:Tb phosphor. TL response depends on Tb concentration and 0.02 is the optimum in the concentration range from 0.01 to 0.10. Using the optimum Tb concentration, we calculated the kinetic parameters of SrB6O10:Tb employing the peak shape method, and suggestedthe phosphor obeying the second order kinetics. TL emission intensity is linearly dependent on the irradiation dose withinthe dose range of 50 ～ 200 Gy.The characteristic Tb3 + ion emission was observed in TL emission spectrum.
