Synthesis and Characterization of Gold Nanoparticles with Plasmon Absorbance Wavelength Tunable from Visible to Near Infrared Region
Figure 2
Effect of seed amount on the nanorod growth. (a) One to five times (a to e) of the normal seed amount (12 μL) cause a shift of the longitudinal plasmon to a longer wavelength. (b) Excess amount of seed > 5 times (f) results in a reduction in the aspect ratio and therefore a shorter SPR wavelength.
