Structural modification of ZnO@Ag2O nanostructures functionalized on optical fiber for room-temperature acetone detection with sub-ppm sensitivity.

In this work, a high-performance, room-temperature-operated acetone gas sensor is developed based on cladding-modified optical fiber functionalized with hierarchical flower-like ZnO@Ag2O nanostructures. Unlike conventional metal-oxide gas sensors operating at elevated temperatures, the formation of a p-n heterojunction...
