Dimensional effect of ZnO nanorods on gas-sensing performance

High aspect ratio ZnO nanorods with controlled diameters and lengths have been successfully prepared. The seed-mediated growth method was used to prepare the samples. An extensive investigation on the performance of the ethanol gas sensor based on ZnO nanorods has been reported. The effects of dimen...

Summary:High aspect ratio ZnO nanorods with controlled diameters and lengths have been successfully prepared. The seed-mediated growth method was used to prepare the samples. An extensive investigation on the performance of the ethanol gas sensor based on ZnO nanorods has been reported. The effects of dimensions on gas-sensing performance and operating temperatures have evidently been discussed. This paper shows that the response to gas has a strong dependence on ZnO nanorod dimensions.
