A substrate for an organic light-emitting device, includes a transparent substrate having an optical index n, bearing, on a first main face, a first transparent or semi-transparent coating of an electrode, referred to as the lower electrode, with a sheet resistance less than or equal to 6&#x3a9;/&#x25a1; and which includes the following stack of layers: an anti-reflection sublayer having a given optical thickness Land having an optical index nsuch that the ratio of nto nis greater than or equal to 6/5; a first metallic layer having a given thickness e; a first separating layer, having a given optical thickness L; a second metallic layer, having an intrinsic electrical conductivity property, and having a given thickness e; and an overlayer for adapting the work function, Lbeing between 20 nm and 120 nm, Lbetween 75 nm and 200 nm, and the sum of the thicknesses e+eof the first and second metallic layers being less than or equal to 40 nm.

The invention relates to a structure for filtering particle-laden gases, comprising an assembly of elements of the honeycomb type linked by a joint or seal, each element incorporating a set of adjacent ducts or channelsof mutually parallel axes and separated by porous walls, which ducts are closed off by plugs at one or other of their ends so as to define entry chambers that open onto a gas intake face and exit chambers opening onto a gas discharge face, in such a way that the gas to be filtered passes through the porous walls, said structure being characterized in that its geometrical centre, in a cross section of the structure perpendicular to its main axis, does not correspond to a symmetry element of an element or of a group of elementsin the assembly.
