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

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)...

description 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.
