A process for depositing a coating on a glass substrate includes co-sputtered simultaneously by a plasma, in one and the same chamber of the vacuum deposition device, a first constituent made of a material consisting of an oxide, a nitride or an oxynitride of a first element and a second constituent consisting of the metallic form of a second element. The process also includes introducing a hydride, a halide or an organic compound of a third element, different than the first element, into the plasma, to recover the substrate covered with the coating comprising the first, second and third elements at the outlet of the device. The coating consists of metal nanoparticles of the second element dispersed in an inorganic matrix of the first and third elements. The coating displays a plasmon absorption peak in the visible region.

The present disclosure relates to a metasurface structural body or the like having a structure for achieving desired optical characteristics. The metasurface structural body includes a base member having a first surface and a second surface opposing each other, and a plurality of antennas as a plurality of fine structures arranged along the first surface. The base member has a base portion and an adjacent portion. The antennas each has a first refractive index and an antenna end surface constituting a part of the first surface. The adjacent portion is provided such that a part thereof is positioned between the antennas, the adjacent portion having a second refractive index different from the first refractive index and an adjacent-portion end surface constituting a remaining part of the first surface. The antenna end surfaces and the adjacent-portion end surface form a flat surface as the first surface.

A glass carrier-attached copper foil is provided that can achieve a desired circuit mounting board that reduces separation of a copper layer at the cut edge even if the copper foil is downsized to dimensions enabling mount of a circuit, and has an intended circuit pattern with a fine pitch. The glass carrier-attached copper foil includes a glass carrier, a release layer, and a copper layer with a thickness of 0.1 to 3.0 m. The glass carrier has, at least on its surface having the copper layer thereon, a plurality of flat regions each having a maximum height Rz of less than 1.0 m as measured in accordance with JIS B 0601-2001 and a rough region having a maximum height Rz of 1.0 to 30.0 m as measured in accordance with JIS B 0601-2001. The rough region has a pattern of lines that define the flat regions.

Platinum films can be obtained by AACVD using a class of Pt-dialkyldithiocarbamates complexes, of the formula Pt(S.sub.2CNR.sub.2), wherein R is independently alkyl, such as isobutyl, aryl, or alkaryl, such as benzyl, particularly as single source precursors. The catalytic performance of the resulting Pt-films allows their use as counter electrodes in dye sensitized solar cells, for example. The efficiency of the AACVD-produced electrodes can be better than a conventionally used Pt-counter electrodes made by the doctor blade's method. The Pt(S.sub.2CNR.sub.2)-derived films have well connected and defect free surface topography and better catalytic performance, likely due to their high conductivity and reflectivity. A simple and low cost method employing such dithiocarbamate precursors can generate Pt-films and electrodes of broad applicability.
