Mechanoluminescent (ML) materials have important applications in the field of mechanical detection. To accelerate the application of ML materials, the expansion of ML materials is essential. Herein, a green ML phosphor KZn(PO3)3:Tb3+ was prepared via a high temperature solid state reaction method. Tb3+ ions occupy the Zn2+ sites, and the defects are generated due to charge compensation, which can serve as the trap center for capturing carriers and are verified by thermoluminescence (TL). The flexible structure framework of KZn(PO3)3 not only provides enough space for defects in the lattice, but also generates great strain energy when applied with forces. KZn(PO3)3:Tb3+ shows a sensitive reaction to different mechanical forces, which indicates it a potential ML material for use in intelligent sensors.

来自 KZn(PO3)3:Tb3+ 的强烈绿色弹性机械发光

机械发光（ML）材料在机械检测领域有着重要的应用。要加速ML材料的应用，ML材料的扩展必不可少。在此，通过高温固相反应法制备了绿色ML荧光粉KZn(PO3)3:Tb3+。Tb3+ 离子占据 Zn2+ 位点，由于电荷补偿而产生缺陷，可作为捕获载流子的陷阱中心，并通过热释光 (TL) 验证。KZn(PO3)3 的柔性结构框架不仅为晶格中的缺陷提供了足够的空间，而且在受力时会产生很大的应变能。KZn(PO3)3:Tb3+ 对不同的机械力表现出敏感的反应，这表明它是一种用于智能传感器的潜在 ML 材料。
