This paper presents the fabrication and application of a notched long-period fiber grating (NLPFG) with an amine-modified surface nanostructure for carbon dioxide (CO₂) gas sensing. The NLPFG with the modified surface nanostructure was fabricated by using inductively coupled plasma (ICP) etching with an Ag nanoparticle etching barrier. The experimental results show that the spectra were changed with the CO₂ gas flow within 12 min. Thereafter, the spectra of the NLPFG remained steady and unchanged. During the absorption process, the transmission loss was decreased by approximately 2.019 dB, and the decreased rate of transmission loss was 0.163 dB/min. The sensitivity was about -0.089 dB/%. These results demonstrate that the NLPFG CO₂ gas sensor has the advantages of steady performance, repeatability, and low cost. Therefore, the NLPFG can be utilized as a reliable CO₂ gas sensor.

本文介绍了一种具有胺改性表面纳米结构的刻痕长周期光纤光栅（NLPFG）用于二氧化碳（CO₂）气体传感的制备及其应用。具有改性表面纳米结构的NLPFG是通过使用带有银纳米颗粒蚀刻阻挡层的电感耦合等离子体（ICP）蚀刻来制备的。实验结果表明，光谱在12分钟内随CO₂气体流量的变化而改变。此后，NLPFG的光谱保持稳定且不变。在吸收过程中，传输损耗降低了约2.019 dB，传输损耗的降低速率为0.163 dB/分钟。灵敏度约为-0.089 dB/%。这些结果表明，NLPFG CO₂气体传感器具有性能稳定、可重复性好和成本低的优点。因此，NLPFG可作为一种可靠的CO₂气体传感器。
