摘要

采用高温固相法制备了BaZrSi

样品，通过X 射线粉末衍射仪、荧光光谱仪和热释光计量计测试了样品的物相结构、荧光光谱、余辉衰减曲线、热释光温度曲线和应力发光特性.测试结果表明：发射光谱峰位于435 nm，具有可重复利用性，属于非破坏性发光，样品应力发光强度与承受的机械应力在一定范围内成正比的规律性.研究表明应力发光的原理与长余辉相似，缺陷势阱捕获的电荷载流子受到外界的影响而释放，与发光中心复合从而产生发光.样品波长属于可见光，可以用作检测应力强度及探测结构破坏位置的图像传感器，从而实现非破坏性应力实时监测及应力可视化.

Abstract

Mechanoluminescence is a type of luminescence caused by the application of mechanical energy to solids. In this paper

powder of BaZrSi

is synthesized by the conventional solid state reaction. Then thermoluminescence and mechanoluminescent properties are studied. Phase and crystal structure of the obtained materials can be determined by X-ray diffraction (XRD). Hence photoluminescent spectrum and mechanoluminescent measurement show that the emission peak is about 435 nm. The mechanoluminescence results present that the intensities of samples are well dependent on the stress

indicating that these mechanoluninescent materials can be potentially used as sensors to detect the dynamic visualization of stress distribution of an object. The results also suggest that

the trap and the worse symmetry of crystal structure are responsible for the mechanoluninescent intensity of BaZrSi
