A photocatalyst layer (TiO) is formed on the surface of a substrate (glass plate) through the intermediary of a monoclinic undercoat layer (ZrO), and no dead layer is substantially present between the photocatalyst layer and the undercoat layer. Also, by providing a peel preventing layer between the substrate and the undercoat layer, it is possible to eliminate film peeling between the photocatalyst layer and the substrate, defects and discoloration. A metal element may be doped in the photocatalyst layer, and it is preferable that the metal element is at least one of Sn, Zn, Mo and Fe. The phrase 'no dead layer is substantially present' means that the thickness of the dead layer is 20 nm or less. The thickness of the photocatalyst layer is preferably from 1 nm to 1,000 nm, more preferably from 1 nm to 500 nm.

Member having photocatalytic function and method for manufacture thereof

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.

Article having photocatalytic activity

An optical fiber collimator which facilitates optical adjustment. The optical fiber collimator includes a gradient index rod lens, and an optical fiber optically connected to the rod lens. An anti-reflection film is formed on one end face of the rod lens. The anti-reflection film has a refractive index which continuously changes from a value substantially equal to that of a center refractive index of the rod lens to a value substantially equal to that of the refractive index of the optical fiber along a film thickness direction of the anti-reflection film. A refractive index matching medium having a refractive index substantially equal to that of the optical fiber bonds the anti-reflection film to the end face of the optical fiber.

Optical fiber collimator and optical fiber collimator array

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;/&square; or lower and the sputtering is conducted while heating the substrate at 230&deg; 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&deg; C. or higher and that the deposited film does not have high photocatalytic activity.
