Bio-inspired optical components
… reflected from this multilayer reflector or Bragg stack were tuned by the application of stimuli which included temperature, change in the solvent environment, pH, salt concentration in the solvent, and electrochemistry.

Doped tungsten oxide nanocrystals for next generation electrochromic windows
… NCs are effectively used for dynamic Bragg stacks with targeted performance of ‘on and off’ reflectance is studied. Dynamic reflectance tuning can affect the color tuning as well as efficient heat blocking. Judicious NC selection of indium tin oxide and WO₃ [subscript -x] NCs from …

Self-assembly and selective swelling in Lamellar block copolymer photonic gels
… 1D swelling turns the lamellar BCP film into a Bragg stack comprised of alternating gel and glass layers, which reflects light in the visible regime. The BCP gels display responsive structural color to a variety of stimuli triggered by the swelling/deswelling of the gel layers, and can be used …

Complex photonic structures in nature: from order to disorder
Structural colours arise from the interaction of visible light with nano-structured materials. The occurrence of such structures in nature has been known for over a century, but it is only in the last few decades that the study of natural photonic structures has fully matured due to the advances in …
