在本研究中，我们报道了一种同时具有机械发光和上转换发光特性的掺Er四元压电半导体CaZnOS：Er~(3+)。在机械刺激下，将CaZnOS：Er3+颗粒包裹在两个聚对苯二甲酸乙二醇酯衬底之间制成的柔性薄膜，可以用肉眼观察到绿光发射。积分发射强度与施加的压力成正比，这使得CaZnOS：Er3+适合于动态压力传感应用。此外，掺杂样品还在近红外(980 Nm)激发下表现出明亮的可见光发射。Er~(3+)的2H11/2，4s3/2→4I15/2跃迁对应的两个上转换发射带之间的荧光强度比对温度变化很敏感。作为一种多功能光学材料，CaZnOS：Er3+不仅可以通过机械诱导发射来显示二维压力分布，还可以通过上转换(UC)L来传感温度。
In this study, we report an Er-doped quaternary piezoelectric semiconductor CaZnOS:Er3+ which shows both mechanoluminescence and upconversion luminescence properties. Under mechanical stimulation, green light emission can be observed by the naked eye from a flexible film fabricated by encapsulating CaZnOS:Er3+ particles between two polyethylene glycol terephthalate substrates. The integral emission intensity is proportional to applied pressure, making CaZnOS:Er3+ suitable for dynamic pressure sensing applications. Moreover, the doped sample also shows bright visible emission with near-infrared (980 nm) excitation. The fluorescence intensity ratio between two upconversion emission bands corresponding to 2H11/2, 4S3/2 → 4I15/2 transitions of Er3+ is sensitive to the variation of temperature. As a multifunctional optical material, CaZnOS:Er3+ could be used to not only visualize two-dimensional pressure distribution, through mechanically induced emission, but also sense temperature via the upconversion (UC) l...
