Tunable three-dimensional ZrO2 photonic crystals replicated from single butterfly wing scales
Abstract
Nature generates 150 000 to 200 000 Lepidoptera species (butterflies and moths). Each has more than one kind of wing scales with three dimensional complicated sub-microstructures. We hereby manipulate the original individual single wing scales (SWSs) of tropical butterfly M. didius and replicate them using ZrO2. The micro-zone
