Fig. 3.

Angle-independent, diffuse, and flexible plasmonic color. (A) Top experimental row is obtained through angle-resolved reflectance measurements using an integrating sphere and fiber optic coupled spectrometer. The bottom row consists of FDTD simulations using a perfectly periodic square array of particles. Adjacent to each dataset is the projected color of the surface obtained using the CIE chromaticity matching functions. (B) Fabrication performed on a thin, flexible layer of PDMS (2 × 3 in.) and (C) masked fabrication of the aluminum particles in the form of the UCF Pegasus logo (2 × 3 in. sample). (D) Microscope images of the surface fabricated on a 100% polyethylene terephthalate fabric.
