SCS is employed for the synthesis of SrTiO₃:Sm3+ (0-11 mol%) nanophosphors. PXRD patterns are in line with the standard JCPDs number 35-0734 confirmed the formation of crystalline SrTiO₃:Sm³⁺ phosphor. Further, the synthesized samples are irradiated by 9 MeV electron beam (10-50 kGy) and analysed using (FTIR) and Raman spectroscopic studies to understand the change in chemical properties. PL spectra of pristine sample exhibited emission peaks at 552, 607 and 732 nm wherein irradiated samples 552 and 732 nm peaks vanishes due to loss of crystallinity by irradiation. Further, two TL glow peaks were observed at 192 and 358 °C in E-beam irradiated samples which shows linear L response with dose. The linear TL response was attributed to release of more number of charge carriers and trap density. The kinetic parameters estimated shows simple trap distribution making SrTiO₃: Sm³⁺(3 mol %) nanophosphor good material for radiation dosimetry applications.

SCS用于合成SrTiO ₃：Sm3 +（0-11 mol％）纳米磷光体。PXRD图与标准JCPD编号35-0734一致，证实形成了晶体SrTiO ₃：Sm ³⁺磷。此外，用9 MeV电子束（10-50 kGy）照射合成的样品，并使用（FTIR）和拉曼光谱研究进行分析，以了解化学性质的变化。原始样品的PL光谱在552、607和732 nm处显示发射峰，其中由于照射导致结晶度降低，被照射的552和732 nm峰消失。此外，在192和358°C的电子束辐照样品中观察到两个TL辉光峰，显示出剂量随线性L响应。线性TL响应归因于更多数量的电荷载流子的释放和陷阱密度。估计的动力学参数显示简单的陷阱分布，使SrTiO ₃：Sm ³⁺（3 mol％）纳米磷光体成为辐射剂量测定应用的良好材料。
