Abstract:
A transparent substrate provided on one of its main surfaces with a stack of thin layers, the stack of layers including the following layers starting from the substrate a first dielectric module of one or more thin layers; a tungsten oxide absorbing layer; a second dielectric module of one or more thin layers; wherein the tungsten oxide includes at least one doping element selected from chemical elements of group 1 according to IUPAC nomenclature.
Abstract:
A conductive support for an OLED, includes a dielectric sublayer, with an optical thickness L1 of greater than 20 nm and less than 180 nm, including a first crystalline contact layer based on zinc oxide, a first silver layer of less than 20 nm, a dielectric separating layer, with an optical thickness L2 of greater than 80 nm and less than 280 nm, including in this order a layer of zinc oxide with a thickness e2, directly on the first silver layer, an optional amorphous layer, based on tin zinc or indium zinc or indium zinc tin oxide with a thickness ei of less than 15 nm, a second layer of zinc oxide, with a thickness ec2, the sum of ec2+e2 being at least 30 nm, a second silver layer of less than 20 nm, a metal overblocker of less than 3 nm, a dielectric electrically conductive overlayer.
