Y(2)O(3):Er(3+) nanorods are synthesized by means of a hydrothermal method and then introduced into a TiO(2) electrode in a dye-sensitized solar cell (DSSC). Y(2)O(3):Er(3+) improves infrared light harvest via up-conversion luminescence and increases the photocurrent of the DSSC. The rare

We demonstrate the optical characteristics of YVO4:Eu3+ phosphor in close proximity to Ag nanofilm to create a highly efficient emitting layer in mirror-type self-emissive displays. The propagating surface plasmon mode induced between the dielectric layer (MgO) and the Ag nanofilm

Typical surface areas of 5 × 5 mm(2) were patterned with high-aspect-ratio micrometer- and submicrometer-sized structures of yttria-stabilized zirconia using a combination of micromolding in capillaries and sol-gel chemistry. The influence of precursor solution concentration and mold geometry on the

We report an upconverting nanomaterial composition, [Y(2)O(3); Yb (2%), Er (1%)], that converts both X-ray and high-fluence NIR irradiation to visible light. This composition is compared to a higher Yb(3+) doped composition, [Y(2)O(3); Yb (10%), Er (1%)], that displays diminished

An extremely thin bilayer electrolyte consisting of yttria-stabilized zirconia (YSZ) and gadolinia-doped ceria (GDC) is successfully fabricated on a sintered NiO-YSZ substrate. Major processing flaws are effectively eliminated by applying local constraints to YSZ nanoparticles, and excellent open circuit voltage
