摘要

本文报道了横向尺寸为~ 200 nm的TiO2颗粒和Au/TiO2杂化颗粒的水胶体的光介电性能。可见光照射下胶体的电导率没有引起可测量的变化，而紫外光(365 nm)的应用导致电导率的光诱导增加高达2%。离子在水中的光生作用，不管粒子是否存在，对光诱导胶体电导率的增加起主要作用。

PHOTODIELECTRIC CHARACTERIZATION OF LIGHT-DRIVEN Au/TiO2 NANOMOTORS IN LIQUID MEDIUM

This article reports on photodielectric properties of hydrocolloids of TiO2 particles and Au/TiO2 hybrid particles of lateral dimension of ∼200 nm. Illumination of the colloids with visible light did not cause measurable changes in their electrical conductivity, while the application of UV (365 nm) light led to photoinduced increase in conductivity of up to 2%. The photogeneration of ions in water, regardless of the presence of the particles, makes a dominant contribution to the photoinduced increase in conductivity of the colloids.
