Figure 2. Optical characteristics of solutions and films of silver nanoparticles tuned by shape. Top are the photographs of (a) yellow, (b) red, and (c) blue solutions and films. The bottom are the normalized extinction spectra of (dashed black line) solutions and (solid red line) different colored zones in the films. The zones in the films are labeled to match the spectra as i, ii, and iii for yellow, purple and blue zones, respectively
