Fig. 5. (a) Photocurrents of Au@CdS NPs modified ITOs irradiated with visible light of 532 nm at –0.3 V (vs. SCE) with electrodeposition times of 0 min, 1 min, 2 min, 3 min, 4 min, 6 min and 9 min. The inset picture shows the color changes of the ITO electrodes under different deposition times. (b) The relationship between photocurrent and electrochemical deposition time. (c) SEM images of Au@CdS NPs with different deposition times on ITO electrodes (scale bar: 100 nm).
