Laser-induced test of photothermal effect of Au@C carbonaceous nanocomposite with laser power density of 0.17 W/cm2. A The relationship between temperature and irradiation time for the aqueous solution of Au@C nanostructures with different thicknesses: bare Au nanorods with no carbonaceous coating, ~ 6 nm, ~ 15 nm, and ~ 23 nm, in which the concentration of each system was adjusted to give an extinction intensity of 1.0 at 800 nm. B Photothermal images of Au@C carbonaceous nanostructures represent different times at (a) 30, (b) 60, (c) 90, (d)180, (e) 360 and (f) 840 seconds under 0.17 W/cm−2 irradiation
