赋予单一材料多种类型的发光，即对不同的刺激表现出同时的光学响应，在各个领域都至关重要。利用3D打印技术和纤维纺丝技术结合异质结ZnS/CaZnOS:Mn ²⁺机械光子材料，构建了基于光致发光（PL）和机械发光（ML）的多功能传感平台。ML 活性颗粒嵌入微米尺寸的纤维素纤维中，用于能够发射由机械力驱动的光的柔性光学器件。还制造了单独修改的 3D 打印硬单元，这些单元在响应机械变形（例如冲击和摩擦）时表现出强烈的 ML。重要的是，它们还可以实现高达约 100 bar 的低压传感，这是以前任何其他光学传感技术都无法达到的范围。^{此外，基于材料的PL开发的光学压力计表现出约6.20 nm GPa -1}的优异高压灵敏度。使用该传感平台，可以实现四种温度检测模式：激发带光谱偏移、发射带光谱偏移、带宽展宽和寿命缩短。这项工作支持大规模生产与科学和工业工具和设备集成的机器学习主动机械和光电零件的可能性。

Mechanoluminescence and Photoluminescence Heterojunction for Superior Multimode Sensing Platform of Friction, Force, Pressure, and Temperature in Fibers and 3D-Printed Polymers

Endowing a single material with various types of luminescence, that is, exhibiting a simultaneous optical response to different stimuli, is vital in various fields. A photoluminescence (PL)- and mechanoluminescence (ML)-based multifunctional sensing platform is built by combining heterojunctioned ZnS/CaZnOS:Mn²⁺ mechano-photonic materials using a 3D-printing technique and fiber spinning. ML-active particles are embedded in micrometer-sized cellulose fibers for flexible optical devices capable of emitting light driven by mechanical force. Individually modified 3D-printed hard units that exhibit intense ML in response to mechanical deformation, such as impact and friction, are also fabricated. Importantly, they also allow low-pressure sensing up to ≈100 bar, a range previously inaccessible by any other optical sensing technique. Moreover, the developed optical manometer based on the PL of the materials demonstrates a superior high-pressure sensitivity of ≈6.20 nm GPa⁻¹. Using this sensing platform, four modes of temperature detection can be achieved: excitation-band spectral shifts, emission-band spectral shifts, bandwidth broadening, and lifetime shortening. This work supports the possibility of mass production of ML-active mechanical and optoelectronic parts integrated with scientific and industrial tools and apparatus.
