Figure 5From: Size-Controlled Synthesis of Colloidal Gold Nanoparticles at Room Temperature Under the Influence of Glow DischargeTypical TEM images and the corresponding size distributions of colloidal Au nanoparticles synthesized by varying the initial concentration of the aqueous HAuCl4 solutions: a 1.0 mM, Av = 5.88 nm, SD = 1.27 nm; b 1.5 mM, Av = 7.95 nm, SD = 1.60 nm; c 2.0 mM, Av = 9.84 nm, SD = 1.67 nm.Scale bar: 50 nm. Av is the average particle size, and SD denotes the standard deviation of the size distributionBack to article page
