Popis: $$\hbox {Zn}_{1-x}\hbox {Sn}_{x}\hbox {O}$$ ( $$x=0$$ , 0.05, 0.10, 0.15, 0.20) nanostructures have been grown through the successive ionic layer adsorption and reaction method. The structural, morphological and compositional properties of the nanostructures have been characterized through X-ray diffraction, scanning electron microscope and energy dispersive X-ray analysis, respectively. The NO gas sensing properties of sensors to 20 ppb have been systematically investigated in the dark and under UV light irradiation. A $$\hbox {Zn}_{0.90}\hbox {Sn}_{0.10}\hbox {O}$$ sensor has exhibited the highest response for 20 ppb NO gas compared with other sensors. The sensor response has increased from 1.9 to 43% depending on the UV light irradiation for the $$\hbox {Zn}_{0.90}\hbox {Sn}_{0.10}\hbox {O}$$ sensor. $$\hbox {Zn}_{0.90}\hbox {Sn}_{0.10}\hbox {O}$$ nanostructure can be used as a suitable gas sensor material for detection of low concentration levels of NO gas.
