摘要

当钯及其合金作为传感层时，侧面抛光光纤传感器对氢具有很高的选择性。采用模态方法对光纤氢传感器进行设计研究。钯钇(PdY)合金中钇的存在降低了氢传感器的开裂和起泡效应。侧磨纤维芯与钯钇合金(PdY)之间存在聚四氟乙烯，影响了灵敏度。优化了聚四氟乙烯和钯钇合金层的厚度，以获得更高的灵敏度

Effect of Teflon buffer on PdY alloy deposited Side Polished Fiber Hydrogen Sensor

Side polished fiber sensor is highly selective for hydrogen when Palladium and its alloy are playing the role of sensing layer. To design study of this fiber hydrogen sensor apply the modal approach. The presence of yttrium in palladium yttrium (PdY) alloy reducing the cracking and blistering effect of hydrogen sensor. The presence of Teflon between core of the side polished fiber and palladium yttrium alloy (PdY) influences the sensitivity. The thickness of Teflon and palladium yttrium alloy layers are optimized to achieve higher sensitivity
