Figure 4.

Optical reflectance spectra of SiNW arrays. The black square line, red dot line, and blue up-triangle line represent the spectra of SiNW arrays decorated with AgNPs with the diameter of 19, 23, and 26 nm, respectively. The green down-triangle line represents the reflectance of bare SiNW array without AgNPs.
