Black phosphorous (BP), in the recent decade, has attracted the attention of researchers as a potential sensing material due to its exceptional physical and chemical properties. This review provides a...
The development of a new type of hybrid material comprising naphthalene-based π-conjugated amine (NBA) and zinc oxide (ZnO) nanohybrid, grown in situ on polydimethylsiloxane (PDMS) flexible substrate, is explored. The morphology of the nanohybrids is controlled by optimizing growth time of the hydrothermal reaction. The CO 2 sensor utilizing NBA−ZnO nanohybrids shows outstanding sensing performance with a maximum response of ∼9% to 500 ppm of CO 2 at room temperature and a comparatively fast response/recovery time (∼3/6 min). The sensor has excellent mechanical flexibility with consistent sensing performance under bending/relaxing process. Hydrophobic nature of the NBA provides less humidity effect on the sensing performance of the NBA−ZnO nanohybrids, which make it suitable for room-temperature application. Also, the presence of layer-by-layer assembly in the NBA−ZnO nanohybrids provides a superior path for carrier transport, which reduces the response and recovery time. All these results indicate that NBA−ZnO nanohybrid is a promising material for room temperature CO 2 sensing application.
We report a detailed correlation analysis of the size, shape, and distribution of Au nanoparticles (NPs) on fine-tuning of localized surface plasmon resonance and optical absorption cross-section.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
