Light absorption with branched gold cauliflower-like nanostructure arrays

A visible and near-infrared broadband light absorber of cone-shaped metallic cavities

“…light-harvesting and light-emitting devices. BLAs are made from metallic nanoparticle/polymer film complexes, 1,2) metallic gratings, 3,4) metallic nanogrooves, [5][6][7][8] metallic nanoisland films, 9,10) nanocones, [11][12][13][14][15][16][17][18][19][20][21] metasurfaces, [22][23][24] nanoparticles, [25][26][27] and designed multilayers. 28,29) Some natural nanostructures can be used as BLA templates.…”
