Abstract:

Au nanoshuttles(Au NSs) with arrow-head were synthesized via wet chemical method by adjusting the concentration of chemical precursors in the solution. The crystal structure and optical properties of Au nanoshuttles were researched by different characterization methods including transmission electron microscopy, UV-Vis-NIR absorption spectra and SERS spectra, etc. At the same time, the growth mechanism of Au nanoshuttles was discussed. Au nanoshuttles have good photothermal properties compared with Au nanorods. The anisotropic Au nanoshuttles with arrow ends feature the local surface plasmon resonance optical properties and possess more advantages than the metal materials with other morphology when they are used in the applications about enhanced local electric field and photothermal conversion. In addition, their photothermal conversion efficiency was calculated. The effect of arrow morphology on the photothermal properties of Au nanoshuttles was disscussed.

Key words: Au nanoshuttle, Surface plasmon resonance, Optical property, Photothermal conversion efficiency
