| 中文摘要 | surface photovoltage spectra (sps) measurements of tio2 show that a large surface state density is present on the tio2 nanoparticles and these surface states can be efficiently decreased by sensitization using us nanoparticles as well as by suitable heat treatment. the photoelectrochemical behavior of the bare tio2 thin film indicates that the mechanism of photoelectron transport is controlled by the trapping/detrapping properties of surface states within the thin films, the slow photocurrent response upon the illumination can be explained by the trap saturation effect. for a tio2 nanoparticulate thin film sensitized using us nanoparticles, the slow photocurrent response disappears and the steady-state photocurrent increases drastically, which suggests that photosensitization can decrease the effect of surface states on photocurrent response. |
