NaBaBO₃ samples incorporated with various concentration of Ce³⁺ were prepared by combustion method. The influences of rare earth doping in synthesized samples were analyzed by X-ray diffraction (XRD). Optimum doping concentration of NaBaBO₃:Ce³⁺ is 0.5 %. Thermoluminescence (TL) kinetic analysis using T_m-T_stop, initial rise (IR), variable heating rate (VHR) and glow curve deconvolution (GCD) methods were performed on the glow curves of NaBaBO₃:Ce³⁺ phosphor material. The T_m-T_stop analysis revealed that the whole glow curve measured without preheat of the prepared sample is composed of at least six overlapping glow peaks. The number of the glow peaks required to provide best fit to the glow curves of the sample are also estimated using GCD method and one found six glow peaks at all doses (FOM ≤ 1.84 %), which are similar to those from T_m-T_stop analysis. The dose response of NaBaBO₃:Ce³⁺ phosphor sample exposed to beta irradiation is linear up to 10 Gy. The results from experiments indicates that main dosimetric peak of NaBaBO₃:Ce³⁺ follows first order kinetic model, which was also supported by dose response plot. The Z effective value of this phosphor is calculated to be 46.66. Present findings confirm that NaBaBO₃:Ce³⁺ phosphor sample is a promising candidate for applications in environmental dosimetry as one depicts good TL dose response with adequate sensitivity and linearity.

通过燃烧法制备了掺有各种浓度的Ce ^3+的NaBaBO ₃样品。通过X射线衍射（XRD）分析了稀土掺杂对合成样品的影响。NaBaBO ₃：Ce ^3+的最佳掺杂浓度为0.5％。在NaBaBO ₃：Ce ³⁺荧光粉材料的辉光曲线上进行了使用T _m -T_停止，初始上升（IR），可变加热速率（VHR）和辉光曲线解卷积（GCD）方法的热致发光（TL）动力学分析。T _m -T_停止分析表明，在没有预热的情况下测得的整个辉光曲线至少由六个重叠的辉光峰组成。还使用GCD方法估算了与样品的辉光曲线最匹配所需的辉光峰数，发现一个在所有剂量下（FOM≤1.84％）的六个辉光峰，与T _m -T相似。_停止分析。暴露于β射线的NaBaBO ₃：Ce ³⁺荧光粉样品的剂量响应在高达10 Gy的范围内呈线性关系。实验结果表明，NaBaBO ₃：Ce ^3+的主要剂量峰遵循一阶动力学模型，该模型也得到剂量响应图的支持。计算出该磷光体的Z有效值为46.66。目前的发现证实，NaBaBO ₃：Ce ³⁺荧光粉样品是在环境剂量测定中应用的有前途的候选者，因为它描绘了良好的TL剂量响应以及足够的灵敏度和线性。
