“…Colored transparent wood is attractive for load-bearing aesthetic design applications such as colorful windows, lighting devices, design furniture, etc. Direct monomer infiltration and polymerization in native wood would also result in C-TW, although in native wood color from lignin and extractives. , White delignified/bleached wood provides more design freedom since pigments, dyes, and inorganic nanoparticles with a structural color , can be added. For example, red C-TW was prepared by incorporation of the Rhodamine 6G (Rh6G) organic dye molecules in the wood structure .…”

“…Wood has been functionalized with PNPs for water treatment applications, either as filters or for solar steam generation, , but never for coloration purposes where low particle size variation and good dispersion are required . To the best of our knowledge, structural coloration of wood has only been proposed as surface coatings of photonic crystals , or alternating layers of mica and titania . Such structures display angle-dependent colors, unlike PNP coloration.…”

Wood is an eco-friendly and abundant substrate and a candidate for functionalization by large-scale nanotechnologies. Infiltration of nanoparticles into wood, however, is hampered by the hierarchically structured and interconnected fibers in wood. In this work, delignified wood is impregnated with gold and silver salts, which are reduced in situ to plasmonic nanoparticles via microwave-assisted synthesis. Transparent biocomposites are produced from nanoparticle-containing wood in the form of load-bearing materials with structural color. The coloration stems from nanoparticle surface plasmons, which require low size dispersity and particle separation. Delignified wood functions as a green reducing agent and a reinforcing scaffold to which the nanoparticles attach, predesigning their distribution on the surface of fibrous "tubes". The nanoscale structure is investigated using scanning transmission electron microscopy (STEM), energydispersive spectroscopy (EDS), and Raman microscopy to determine particle size, particle distribution, and structure−property relationships. Optical properties, including response to polarized light, are of particular interest.
