Abstract

Nanocrystalline undoped and Sb2O3 doped (0.1 to 0.5 wt%) ZnO powders were synthesized by solution-combustion method using glucose, sucrose and nitrate salts as precursors. The undoped and doped ZnO particles were structurally characterized using X-ray diffractometer and transmission electron microscope. The average particles size of the ZnO powder was found to be 40 nm. Interestingly, sensors made from antimony doped ZnO powder showed better alcohol sensing (5-50 ppm) properties and long-term stability than those for undoped ZnO powder. It was found that 0.25 wt% Sb2O3 doped ZnO sensors exhibited the optimum alcohol sensing behavior and excellent response and recovery times.
