Caption
(a) An all-polysaccharide multilayer reflector fabricated by stacking 50 layers under conditions yielding an average layer thickness of ~85 nm and an additional 50 layers under conditions yielding ~117 nm. (b) The corresponding reflectance spectrum exhibiting two distinct reflection peaks. (c) An illustration showing the coexistence of narrow- and wide-pitch multilayer regions. (d) An all-polysaccharide multilayer reflector fabricated by gradually increasing the electrodeposition time from conditions corresponding to an average layer thickness of ~85 nm, yielding a total of 200 layers with a graded pitch. (e) The corresponding reflectance spectrum exhibiting broadband high reflectivity across the visible range. (f) Schematic illustration of the gradient-pitch multilayer architecture. (g) A patterned electrode and the corresponding patterned all-polysaccharide multilayer reflector fabricated using the electrode pattern. (h) Schematic illustration showing spatially selective reflection of different wavelengths arising from the locally controlled multilayer pitch on patterned electrodes.
