A CdSiO₃:Tb³⁺ deep trap phosphor was prepared by a sol–gel method. The structural information of the prepared phosphors was characterized by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The optical properties of the Tb³⁺-doped CdSiO₃ nanophosphors were investigated by fluorescence spectrophotometry. The afterglow time was more than 10.3 h in the case of Tb³⁺ doping. The stress–strain of this elastomer was enhanced after the phosphor was compounded with PDMS, and the energy release in the trap was accelerated under external force after applying stress to it, and this composite elastomer may possess mechanoluminescent properties.

具有深陷阱的机械发光CdSiO3:Tb3+/PDMS复合弹性体

采用溶胶-凝胶法制备了CdSiO ₃ :Tb ^{3+深陷阱荧光粉。}通过粉末X射线衍射（XRD）和扫描电子显微镜（SEM）对所制备的荧光粉的结构信息进行了表征。采用荧光分光光度法研究了Tb ³⁺掺杂CdSiO _{3纳米荧光粉的光学性质。}^{Tb 3+}掺杂的情况下余辉时间超过10.3 h 。荧光粉与PDMS复合后，该弹性体的应力应变增强，施加应力后在外力作用下加速了陷阱中的能量释放，这种复合弹性体可能具有机械发光特性。
