<p>A vacuum enclosure which is defined by a wall having inner and outer surfaces, where the inner surface is in contact with the vacuum and the outer surface is in contact with ambient air, is characterized by presence therein of a getter for undesired gaseous contaminants, which comprises a substrate (either integral with the inner surface or not), and deposited thereon by vacuum deposition a thin-layer laminate including (±) at least one layer of substance(s) selected from the group consisting of platinum group metals and oxides thereof, and (²) at least one porous hydrophilic layer. A corresponding layered structure having utility as a getter is also part of the invention.</p> |
