摘要

制备了金属有机骨架（MOFs）装饰低语廊模式（WGM）微腔，用于挥发性有机化合物（VOCs）的传感。该复合微腔对VOCs吸附引起的折射率变化敏感，灵敏度为9.74 nm/RIU，检出限为3.30×10-3 RIU，重现性强，对湿度和温度变化具有良好的耐受性。

Metal–organic framework decorated whispering-gallery-mode microsphere cavities for VOC sensing†

Metal–organic framework (MOF) decorated whispering gallery mode (WGM) microcavities are prepared for volatile organic compound (VOC) sensing. The composite microcavity is sensitive to the refractive index changes caused by VOC adsorptions, with a sensitivity of 9.74 nm RIU⁻¹, a detection limit of 3.30 × 10⁻³ RIU, robust reproducibility, and good resistance to humidity or temperature variations.
