Journal ArticleDOI
Multifunctional Au-ZnO Plasmonic Nanostructures for Enhanced UV Photodetector and Room Temperature NO Sensing Devices
TL;DR: The sensing response of Au-ZnO nancomposite is enhanced both in UV and visible region, as compared to control ZnO, and the sensitivity is observed to be higher in the visible region due to the LSPR effect of Au NPs.
Journal ArticleDOI
Chemically reduced graphene oxide for ammonia detection at room temperature.
TL;DR: The synthesis of chemically reduced GO using NaBH4 and its performance for ammonia detection at room temperature and its use to manufacture a new generation of low-power portable ammonia sensors is reported.
Journal ArticleDOI
Hierarchical nanostructured WO3-SnO2 for selective sensing of volatile organic compounds.
TL;DR: A mixed metal oxide WO3-SnO2 nanostructured material synthesized in situ by a simple, single-step, one-pot hydrothermal method at 200 °C in 12 h is reported to demonstrate its superior sensing behavior towards volatile organic compounds (VOCs) such as ammonia, ethanol and acetone.
Journal ArticleDOI
