摘要:
An organic electroluminescent device having the hole-transport layer in which the hole-transport material is dispersed in the resin binder having a glass transition temperature of not less than 170.degree. C. Since the above organic electroluminescent device has the hole-transport layer exhibiting sufficient durability and higher hole-transport property, it is excellent in luminous efficiency, luminance and stability.

摘要:
A hydrogen permeable structure includes a base material (1) including porous ceramic, and a hydrogen permeable film (2) formed on the base material (1), including palladium (Pd) and at least one element other than palladium and having an amount of hydrogen dissolution at a prescribed temperature smaller than that of palladium alone. The hydrogen permeable film (2) is formed on the surface of the porous ceramic base by a physical vapor deposition technique after any pin holes in the surface of the base have been filled with a porous oxide material.
摘要:
The invention provides a hydrogen permeable structure, which can effectively prevent peeling-off of a hydrogen permeable film and hence has higher durability, and a method of manufacturing the structure. The hydrogen permeable structure has a hydrogen permeable film formed on the surface of or inside a porous support, having a thickness of not more than 2 &mgr;m, and containing palladium (Pd). The hydrogen permeable film is formed on the surface of or inside the porous support by supplying a Pd-containing solution and a reducing feed material from opposite sides of the porous support.
摘要:
A substance separation structure comprises a base material including a porous material having a continuous hole with an opening of the hole formed on at least one surface, a porous layer, formed to fill up the opening, having a hole smaller than the hole of the base material and a permeable membrane of not more than 1 &mgr;m in thickness formed on at least one surface of the base material formed with the porous layer to selectively permeate ions or neutral elements or molecules, and the surface roughness of at least one surface of the base material formed with the porous layer is not more than 0.3 &mgr;m in Rmax. The surface of the base material is polished with abrasive grains containing a porous material so that the opening of the base material can be filled up with the porous layer, and the permeable membrane is formed by ion plating.
