Near infrared light enhanced room-temperature NO2 gas sensing by hierarchical ZnO nanorods functionalized with PbS quantum dots

•Room-temperature NO2 sensors based on PbS/ZnO nanocomposites.•Near infrared (NIR) light was utilized in NO2 sensing for the first time.•NIR enhanced the radial modulation of the conduction channel of the ZnO nanorods. Here we report the near infrared light (NIR) activated room-temperature NO2 gas s...
