Photonic Crystals: Exploiting Nanoroughness on Holographically Patterned Three-Dimensional Photonic Crystals (Adv. Funct. Mater. 14/2012)
On page 2980, Shu Yang and co-workers report the fabrication of microstructured diamond photonic crystals with controllable nanoroughness made by varying the processing conditions, which include the degree of photocrosslinking density and the choice of solvent for developing and rinsing during the holographic lithography process. The resulting dual-scale photonic crystals exhibit structural color together with superhydrophobicity, thus mimicking butterfly wings, and have significantly enhanced dye adsorption compared to that of a smooth-surfaced crystal.
