A fundamental question regarding light scattering is how whiteness, generated from multiple scattering, can be obtained thin layers of materials. This challenge arises the phenomenon optical crowding, whereby, for scatterers packed with filling fractions higher than ~30%, reflectance drastically reduced due to near-field coupling between scatterers. Here we show that extreme birefringence isoxanthopterin nanospheres overcomes crowding effects, enabling and brilliant whiteness ultra-thin...
Numerous bio-organisms employ template-assisted crystallization of molecular solids to yield crystal morphologies with unique optical properties that are difficult reproduce synthetically. Here, a facile procedure is presented deposit bio-inspired birefringent crystals xanthine derivatives on template single-crystal quartz. Crystalline sheets several millimeters in length, hundred micrometers width, and 300-600 nm thick, obtained. The characterized well-defined orientation both out the...
Abstract Aligned growth of planar semiconductor nanowires (NWs) on crystalline substrates has been widely demonstrated during the past two decades and was used for fabrication a large variety devices. However, dependence single‐crystal is major obstacle in way implementing NW‐based applications today's silicon‐ glass‐based technologies. Here, guided NWs along nanoscale‐depth scratches, created nonlithographic process amorphous oxidized silicon wafers soda‐lime glass. Scratches are few...
Spherical particles with diameters within the wavelength of visible light, known as spherulites, manipulate light uniquely due to their spatial organization and structural birefringence. Most crystalline spherulites are branched, composed metals, alloys, semi-crystalline polymers. Recently, a different spherulite architecture is discovered in vision systems decapod crustaceans - core-shell highly birefringent (
