Image of FIG. 1.
FIG. 1.

Optical and SEM image of the light detection device. (a) Optical image of the device. The left and right parts correspond to SWNT film without or with gold NPs, respectively. The boundary can be clearly seen at the middle. (b) Typical SEM image of SWNT film before the deposition of gold NPs. (c) Typical SEM image of SWNT film decorated with gold NPs. (d) Typical SEM image of SWNT film decorated with gold NRs.

Image of FIG. 2.
FIG. 2.

(a) curve of the device with and without illumination of white light. (b) Dynamic characteristics of the induced for devices decorated with gold NPs when the light is turned on and off. From top to bottom, the light corresponds to blue, green, red, and white, respectively. The two curves in each group corresponds to the full and half power of the incident light. There are offset in these curves for clarity. (c) Comparison of the responsivities for devices with gold NPs or NRs.

Image of FIG. 3.
FIG. 3.

(a) Schematic showing the mechanism of the induced , which is due to the temperature difference between the SWNT film and that film with gold NPs or NRs. (b) Experimental results of the temperature for the two parts when white light is on and off. A clear difference can be observed when light is turned on and this difference disappears when the light is turned off. (c) The absorbance spectra of gold NPs and NRs.
