| 中文摘要 | three kinds of tio2 nanostructured thin films and their cds-sensitized films, consisting of different sizes of tio2 nanoparticles prepared with different methods, have been investigated. the surface photovoltage spectra (sps) measurements indicate that the density of surface states on tio2 is likely dependent upon the details of prepared methods. tio2 particles prepared from basic sol have more surface states than that prepared from acidic sol. when the tio2 thin films prepared using the tio2 sols were sensitized by cds particles, the sps responses relative to the surface states on tio2 from 350 to 800 nm were decreased. the photoelectrochemical properties of nanostructured tio2 electrodes suggest that the fewer the surface states and the smaller the particle sizes of tio2, the larger the photocurrent response. for cds sensitized tio2 thin film electrode, it is shown that the semiconductor sensitization is an efficient way to decrease the influence of surface states on the charge separation, and can improve the intensity of photocurrent response.
