Abstract

This paper proposes a novel multicomponent gas-sensing optical fiber probe system. It utilizes a precisely engineered Platinum-coated capillary fabricated via Atomic Layer Deposition (ALD) technology as the core for enhanced Raman spectroscopy, marking the first application of ALD in creating such a structure for gas Raman sensing. The noble metal capillary gas Raman probe demonstrates a low detection limit of 55 ppm for CO₂ with a 30 s exposure time and good repeatability in multicomponent gas sensing. The capillary exhibits excellent stability, environmental resistance, and a large core diameter, enabling a rapid gas exchange rate and making it suitable for practical applications.

基于铂涂层毛细管增强拉曼光谱的多组分气体传感光纤探针系统

本文提出了一种新型多组分气体传感光纤探针系统。该系统利用通过原子层沉积（ALD）技术制造的精密铂涂层毛细管作为增强拉曼光谱的核心，这是首次应用原子层沉积技术制造出用于气体拉曼传感的此类结构。贵金属毛细管气体拉曼探针在 30 秒曝光时间内对二氧化碳的检测限低至 55 ppm，并且在多组分气体传感中具有良好的重复性。该毛细管具有出色的稳定性、耐环境性和较大的管芯直径，可实现快速气体交换，适合实际应用。
