In this study, we proposed the one-dimensional (1D) photonic crystals (PCs) chlorobenzene sensor assembled by TiO₂, UiO-66 and graphene oxide (GO). The originality of the sensor is that the PCs structure alternately assembled by TiO₂, UiO-66 and GO. The unique structure of the sensor can enhance the selectivity and sensibility of the sensor to chlorobenzene vapors because the mesoporous photonic structure built by UiO-66 nanoparticles and GO sheets can generate the van der Waals force and the π-π stacking interaction. The experiment results also demonstrated the detection limits of chlorobenzene vapors can reach 13 ppm and the distinct reflection spectra red-shift of 17.8 nm within 800 ms when exposed to chlorobenzene vapors stream. And that the refection peak displacement errors of the sensor are within 1.5 nm after repeatedly sensing experiments to chlorobenzene vapors. Moreover, thanks to the excellent stability of UiO-66 and GO, the sensor can maintain original performances after ultrasound and heat treatment. With excellent performances, the 1D PCs sensor can be the promising candidate of high-performance chlorobenzene sensors for environmental quality monitoring.

在这项研究中，我们提出了由TiO ₂，UiO-66和氧化石墨烯（GO）组装的一维（1D）光子晶体（PCs）氯苯传感器。传感器的独创性是PC结构由TiO ₂，UiO-66和GO交替组装而成。传感器的独特结构可以增强传感器对氯苯蒸气的选择性和敏感性，因为由UiO-66纳米颗粒和GO片材构建的中孔光子结构可以产生范德华力和π-π堆积相互作用。实验结果还表明，氯苯蒸气的检出限可以达到13 ppm，并且明显的反射光谱红移为17.8。 当暴露于氯苯蒸气流时，在800毫秒内达到100 nm。并且在 对氯苯蒸气进行多次感测实验后，传感器的反射峰位移误差在1.5 nm以内。此外，由于UiO-66和GO的出色稳定性，该传感器在超声和热处理后仍可保持原始性能。一维PC传感器具有出色的性能，可以成为用于环境质量监测的高性能氯苯传感器的有前途的候选者。
