Compared with conventional destructive mechanoluminescent materials, trap-controlled mechanoluminescent materials generally preserve high structural integrity and repeatability during the mechanoluminescent process. The trap-controlled mechanoluminescent materials have attracted recent attention in diverse fields of stress sensors, mechano-driven lighting and displays. The development of high-performance trap-controlled mechanoluminescent materials is of great significance to promote the application of mechanoluminescence. This paper was to investigate a trap-controlled reproducible mechanoluminescent material, i.e., Ca2Ga2GeO7:Pr3+, and analyze its luminescent properties by the measurements of X-ray diffraction patterns, diffuse reflection spectra, phosphorescent decay curves, photoluminescence, mechanoluminescence and thermoluminescence. The emission peaks of photoluminescence and mechanoluminescenc are the same at 488 nm, 610 nm and 648 nm, corresponding to the energy level transition of Pr3+ of 3H4→3P0, 3H4→1D2 and 3F2→3P0, respectively. A slow-decaying mechanoluminescent behavior occurs when the continuous frictional stimulation and the mechanoluminescent intensity increase linearly with increasing the pressure. According to the thermoluminescent measurement, the slow-decaying mechanoluminescence is attributed to existence of deep traps. The deep traps provide an electron replenishment for shallow traps for Ca2Ga2GeO7:Pr3+ under continuous stress stimulation. This paper may provide a material-and-experimental basis for the development and application of high-performance trap-controlled mechanoluminescent materials.

相比于传统的破坏型应力发光材料,陷阱控制型应力发光材料在应力发光过程中具有良好的结构完整性和应力发光可重复性等优势,已在应力传感器、应力驱动的照明和显示器等领域展现出应用潜力,高性能陷阱控制型应力发光材料的开发对推动应力发光的应用进程具有重要意义。本工作研究了新型陷阱控制型应力发光材料Ca2Ga2GeO7:Pr3+,通过测量XRD谱、漫反射光谱、荧光衰减曲线、发射光谱、应力发光光谱和热释光图谱对其发光特性进行了研究。Ca2Ga2GeO7:Pr3+的光致发光谱和应力发光光谱均具有位于488、610 nm和648 nm的发射峰,分别对应于Pr3+从3H4→3P0、3H4→1D2和3F2→3P0的能级跃迁。我们发现在连续摩擦刺激下其应力发光强度表现出缓慢衰减特性,并且应力发光强度与应力强度还满足线性增长趋势。基于热释光测试的陷阱属性分析表明:Ca2Ga2GeO7:Pr3+缓慢衰减的应力发光特性主要来源于材料中深陷阱的存在,即在连续应力刺激过程中,深陷阱不断地向浅陷阱提供电子补充,使应力发光表现出缓慢衰减特性。这为高性能陷阱控制型应力发光材料的开发和应用提供了材料和实验基础。

相比于传统的破坏型应力发光材料,陷阱控制型应力发光材料在应力发光过程中具有良好的结构完整性和应力发光可重复性等优势,已在应力传感器、应力驱动的照明和显示器等领域展现出应用潜力,高性能陷阱控制型应力发光材料的开发对推动应力发光的应用进程具有重要意义。本工作研究了新型陷阱控制型应力发光材料Ca2Ga2GeO7:Pr3+,通过测量XRD谱、漫反射光谱、荧光衰减曲线、发射光谱、应力发光光谱和热释光图谱对其发光特性进行了研究。Ca2Ga2GeO7:Pr3+的光致发光谱和应力发光光谱均具有位于488、610 nm和648 nm的发射峰,分别对应于Pr3+从3H4→3P0、3H4→1D2和3F2→3P0的能级跃迁。我们发现在连续摩擦刺激下其应力发光强度表现出缓慢衰减特性,并且应力发光强度与应力强度还满足线性增长趋势。基于热释光测试的陷阱属性分析表明:Ca2Ga2GeO7:Pr3+缓慢衰减的应力发光特性主要来源于材料中深陷阱的存在,即在连续应力刺激过程中,深陷阱不断地向浅陷阱提供电子补充,使应力发光表现出缓慢衰减特性。这为高性能陷阱控制型应力发光材料的开发和应用提供了材料和实验基础。

Compared with conventional destructive mechanoluminescent materials, trap-controlled mechanoluminescent materials generally preserve high structural integrity and repeatability during the mechanoluminescent process. The trap-controlled mechanoluminescent materials have attracted recent attention in diverse fields of stress sensors, mechano-driven lighting and displays. The development of high-performance trap-controlled mechanoluminescent materials is of great significance to promote the application of mechanoluminescence. This paper was to investigate a trap-controlled reproducible mechanoluminescent material, i.e., Ca2Ga2GeO7:Pr3+, and analyze its luminescent properties by the measurements of X-ray diffraction patterns, diffuse reflection spectra, phosphorescent decay curves, photoluminescence, mechanoluminescence and thermoluminescence. The emission peaks of photoluminescence and mechanoluminescenc are the same at 488 nm, 610 nm and 648 nm, corresponding to the energy level transition of Pr3+ of 3H4→3P0, 3H4→1D2 and 3F2→3P0, respectively. A slow-decaying mechanoluminescent behavior occurs when the continuous frictional stimulation and the mechanoluminescent intensity increase linearly with increasing the pressure. According to the thermoluminescent measurement, the slow-decaying mechanoluminescence is attributed to existence of deep traps. The deep traps provide an electron replenishment for shallow traps for Ca2Ga2GeO7:Pr3+ under continuous stress stimulation. This paper may provide a material-and-experimental basis for the development and application of high-performance trap-controlled mechanoluminescent materials.
