我们介绍了一种具有Au/Ta2O5/Pd层的铂涂层、异质芯、光纤表面等离子体共振（SPR）氢传感器，用于长期氢探测。在室温条件下储存1个月和2个月后，氢感仍然存在。为了测试铂涂层的效果，分别制备了镀有Au和pd的光纤氢传感器。在抑制传感器灵敏度和响应时间退化方面，镀有Pt薄膜的传感器优于镀有Au/Ta2O5/Pd或Au/Ta2O5/Pd/Au多层薄膜的传感器。
We introduce a Pt-coated, hetero-core, optical fiber-surface plasmon resonance (SPR) hydrogen sensor featuring layers of Au/Ta2O5/Pd for long-term hydrogen detection. Hydrogen sensing persisted after 1- and 2-month storage at room temperature in air conditioning. To test the effect of Pt coating, sensors coated with Au and Pd-only-based optical fiber hydrogen sensors were prepared. Sensors coated with a thin Pt film were superior to sensors coated with Au/Ta2O5/Pd or Au/Ta2O5/Pd/Au multilayer films with respect to the suppression of sensor sensitivity- and response time deterioration.
