论文摘要
以可靠，快速且具有成本效益的方式检测氢是在绿色经济中大规模实施氢的先决条件。我们将薄膜TA $ _ {1-y} $ PD $ _y $作为有效的光学传感材料，具有极宽的传感范围，涵盖了至少七个数量级的氢压力。 TA $ _ {1-y} $ pd $ _y $ layer的纳米封度抑制了批量存在的一阶相变，并确保没有任何滞后的感应响应。与其他传感材料不同，ta $ _ {1-y} $ pd $ _y $具有特殊属性，可以通过改变PD浓度而不会降低感应材料的敏感性来轻松调节感应范围。结合一个合适的上限层，即使在室温下也可以达到比任何其他已知的薄膜氢传感器的快速响应时间。
Hydrogen detection in a reliable, fast, and cost-effective manner is a prerequisite for the large-scale implementation of hydrogen in a green economy. We present thin film Ta$_{1-y}$Pd$_y$ as effective optical sensing materials with extremely wide sensing ranges covering at least seven orders of magnitude in hydrogen pressure. Nanoconfinement of the Ta$_{1-y}$Pd$_y$ layer suppresses the first-order phase transitions present in bulk and ensures a sensing response free of any hysteresis. Unlike other sensing materials, Ta$_{1-y}$Pd$_y$ features the special property that the sensing range can be easily tuned by varying the Pd concentration without a reduction of the sensitivity of the sensing material. Combined with a suitable capping layer, sub-second response times can be achieved even at room temperature, faster than any other known thin-film hydrogen sensor.
