英文摘要ZnO and Sn-, Ga- and Mn-doped ZnO nanoparticles were prepared by a coprecipitation method, and characterized by scanning electron microscopy (SEM), energy dispersive spectra (EDS), X-ray diffraction (XRD) and Raman spectra. The gas sensing properties were studied using formaldehyde, relative humidity, NH3, toluene and CO as the probes. The results show that all particles have wurtzite ZnO phase, though Sn-ZnO has a relatively smaller particle (and crystallite) size than the other three samples. Gas sensing property tests reveal that the temperature where the gas sensing maximum is gained (T (M)) is changed by different dopants: Sn-ZnO and Mn-ZnO have relatively lower T (M) (similar to 100A degrees C lower) compared with that of pure ZnO, while Ga-ZnO has the same T (M) as pure ZnO except in CO sensing. Thermoluminescence (TL) spectra were used to investigate the mechanism of T (M) change. The peak positions of Ga-ZnO and ZnO are the same at 300-350A degrees C, while that of Sn-ZnO shifts to 250-300A degrees C, which might contribute to the same T (M) of Ga-ZnO and pure ZnO and relatively lower T (M) of Sn-ZnO. In the case of Mn-ZnO, the luminescence emission is evidently limited by its black color.
