| 英文摘要 | Fe-, Ti-, Sn-doped (1.8, 7.4 and 3.4 mol% respectively) and pure ZnO are prepared by hydrothermal method using 10 mol% precursors, whose gas sensing property is studied using formaldehyde as the probe. The results show that the maximum response of pure ZnO to 205 ppm formaldehyde is similar to 43 (at relative humidity 70 +/- 10%) at 400 degrees C. But the gas response maxima shift to 300 degrees C for Fe-ZnO (similar to 52-205 ppm) and Sn-ZnO (similar to 140-205 ppm), and to 200 degrees C for Ti-ZnO (similar to 26-205 ppm). Beyond the maxima, the response of Fe-ZnO is lower than that of pure ZnO, while that of Sn-ZnO is always higher. The morphology, crystal structure, vibration modes, bandgap and crystal defects are studied to investigate the different doping effects on gas sensing property of ZnO. The results show that the secondary phase identified by X-ray diffraction and Raman spectra, and the crystal defects detected by photoluminescence might account for the different sensing behaviors.
