Detection of volatile organic compounds (VOCs) at parts-per-billion (ppb) level is one of the most challenging tasks for miniature gas sensors because of the high requirement on sensitivity and the possible interference from moisture. Herein, for the first time, we present a novel platform based on a hybrid photonic cavity with metal-organic framework (MOF) coatings for VOCs detection. We have fabricated a compact gas sensor with detection limitation ranging from 29 to 99 ppb for various VOCs including styrene, toluene, benzene, propylene and methanol. Compared to the photonic cavity without coating, the MOF-coated solution exhibits a sensitivity enhancement factor up to 1000. The present results have demonstrated great potential of MOF-coated photonic resonators in miniaturized gas sensing applications.
检测十亿分之几（ppb）级别的挥发性有机化合物（VOCs）是微型气体传感器面临的最具挑战性的任务之一，因为其对灵敏度有很高的要求，而且可能会受到湿气的干扰。在此，我们首次提出了一种基于混合光子腔与金属有机骨架（MOF）涂层的新型平台，用于 VOCs 的检测。我们已经制造了一种紧凑的气体传感器，其检测限范围从 29 到 99 ppb，适用于包括苯乙烯、甲苯、苯、丙烯和甲醇在内的各种 VOCs。与未涂层的光子腔相比，MOF 涂层溶液的灵敏度增强因子高达 1000。本研究结果表明，MOF 涂层的光子谐振器在小型气体传感应用中具有很大的潜力。
