摘要： A surface of a glass plate is coated with a first n-type semiconductor film which is a 50 nm-thick niobium oxide film as a primer layer. The primer layer is coated with a 250 nm-thick photocatalyst film comprising titanium oxide. Thus, an article having a photocatalytically active surface is obtained. The two coating films can be formed by sputtering. The first n-type semiconductor film as the primer layer is selected so as to have a larger energy band gap than the titanium oxide. Due to this constitution, more holes are generated near the film surface. This article can be free from the problem of conventional titanium oxide films having photocatalytic activity that it is difficult to generate many surface holes contributing to photocatalytic activity, because electrons and holes generated by charge separation recombine within the film, making it impossible to effectively heighten catalytic activity.
摘要翻译：玻璃板的表面涂覆有作为底漆层的50nm厚的氧化铌膜的第一n型半导体膜。底漆层涂覆有包含氧化钛的250nm厚的光催化剂膜。因此，获得具有光催化活性表面的物品。可以通过溅射形成两个涂膜。选择作为底漆层的第一n型半导体膜具有比氧化钛更大的能带隙。由于这种结构，在膜表面附近产生更多的孔。本发明不含常规的具有光催化活性的氧化钛薄膜的问题，难以产生许多有助于光催化活性的表面空穴，因为电荷分离产生的电子和空穴在膜内复合，使得不可能有效地提高催化活性活动。

摘要： A conductive sinter obtained from a mixture of titanium oxide particles and 2.5% by weight niobium oxide particles is used as a target in direct current sputtering to form a photocatalytically active film mainly comprising titanium oxide on a glass substrate. The target has a surface resistance of 500 &OHgr;/□ or lower and the sputtering is conducted while heating the substrate at 230° C. The photocatalytically active film is based on an amorphous matrix. This process is free from problems of a conventional process in which a photocatalytically active titanium oxide film is deposited by reactive sputtering using titanium metal as a target. The problems are that the substrate needs to be heated to 350° C. or higher and that the deposited film does not have high photocatalytic activity.

The glass member is produced by laminating an antistripping layer made of silicon oxide or the like, a crystalline undercoat layer made of zirconium oxide or the like and a photocatalyst layer made of titanium oxide or the like on the other surface of a glass substrate having a heat reflecting layer formed on one surface thereof.

Likewise, the heat reflecting layer is formed such that the reflection chromaticity (a*, b*) satisfies −15≦a*≦−2 and −10≦b*≦10 and the visible light reflectance is 13% or less, the crystalline undercoat layer is allowed to have a thickness ranging from 2 to 28 nm, and the photocatalyst layer is allowed to have a thickness ranging from 2 to 14 nm, whereby the glass member having a bluish green or green reflection color tone can be produced.

摘要： The present invention provides a method for forming a titanium compound film on a substrate by a sputtering process by use of, in place of a conventional metallic titanium target, a titanium target containing a metal (such as tin or zinc) having two or more times higher sputtering yield in an argon atmosphere than titanium; an article coated with a titanium compound film; and a sputtering target for use in the film coating. The content of tin or zinc in the titanium target containing tin or zinc is preferably in the range of 1 to 45 at %, and further a third metal may be added. These can remove drawbacks in that the film has a low film formation rate and a high output power cannot be applied due to the occurrence of arcing in forming a titanium compound film on the surface of a substrate, such as plate-shaped glass, by a reactive sputtering process.

A photocatalyst layer (TiO2) is formed on the surface of a substrate (glass sheet) through the intermediary of a crystalline undercoat layer (ZrO2), and no dead layer is substantially present between the photocatalyst layer and the undercoat layer.
