Vivid colours in hyperuniform complex-index photonic structures by resonant interference of photonic band gaps and optical band gaps

Abstract

Hyperuniform photonic structures (HPSs) have been doped with complex index materials to increase their reflectivity and colour expression range.

Self-assembly of POSS–Polystyrene Bottlebrush Block Copolymers on an Angle-Robust Selective Absorber for Enhancing the Purity of Reflective Structural Color

“…The color purity was heavily impacted by the long-range order and macroscopic orientation of the nanostructure, and the nanostructures were mediated by controlling the composition and segregation strength of the side chains. − ,− Despite the successes achieved in full color-displayed PCs via self-assembly of the BBCP, to date, there are no reports on the effect of optical substrates on the self-assembly and optical properties of BBCP-based PCs. The addition of highly absorbing dopants can compensate for the degraded color saturation and low reflectance of BBCP-based 1D PCs, and it is involved in modulating photonic band gaps and increasing the refractive index contrast. − However, a combinational process with an absorbing dopant and a BBCP-based PC has been unexplored.…”
