TL;DR: Structural colors traditionally refer to colors arising from the interaction of light with structures with periodicities on the order of the wavelength as mentioned in this paper, and have been broadened to include other colors.

TL;DR: A heat-shrinking method is introduced to produce 3D-printed photonic crystals with a 5x reduction in lattice constants, achieving sub-100-nm features with a full range of colors, including the first multi-color microscopic model of the Eiffel Tower.

TL;DR: In this article, the Eiffel Tower was printed in 3D with a color pixel size of 1.45 microns, using 3D-printed photonic crystals with a 5x reduction in lattice constants (periodicity as small as 280 nm).

TL;DR: In this article, the authors proposed a high speed reprogrammable Sb2S3-based photonic devices, which can be used in future intelligent photonic systems, holographic displays, and micro-spectrometers.
