Image of FIG. 1.
FIG. 1.

The preparation process of monolayered masks consisted of PS nanospheres: application of PS nanospheres onto a water surface (a), consolidation of PS nanospheres (b), and lift off ordered monolayer (c).

FIG. 2.

The diagram of the evaporation and sputtering system.

Image of FIG. 3.
FIG. 3.

Schematic representation of the experimental procedures for fabricating various ordered Ag nanostructures arrays using three fabrication processes (processes I–III): (I) honeycomb arrays of nanodots (A1–A2), A1: perpendicular evaporation on the PS sphere template, A2: removing PS template; (II) nanobowl arrays are obtained after the polymer cores were dissolved in CHCl (A1–A3). (III) nanoring arrays (B1-B2), B1: sputtering is carried out with a certain angle and the PS template is rotating at a certain rate, B2: removing PS template.
