摘要： The present disclosure relates to electrochromic elements and devices including an electrochromic material having one or more optical properties that may be changed upon application of an electric potential. The device may include a conductive nanoparticle layer and/or a buffer layer. Upon provision of an electric potential above a threshold where electron tunneling may occur in the barrier layer, electrons are passed to or from the electrochromic material through the barrier layer resulting in a change to the optical properties of the electrochromic material. An opposite electric potential may be provided to reverse the change in the optical properties.

摘要： The present disclosure relates to an emissive construct, which can be used in various OLED applications, for example, top-emission white organic light-emitting diodes. The emissive construct includes a fluorescent emissive layer, a partial hole-blocking layer, and a phosphorescent emissive. A recombination zone is shared between the fluorescent emissive layer and the phosphorescent emissive layer, such that the thickness of the partial hole-blocking layer is less than about one-third of the thickness of the recombination zone.

摘要： The present disclosure relates to electrochromic devices including an insulating layer and at least one electrochromic material having one or more optical properties that may be changed upon application of an electric potential. The device may include a conductive nanoparticle layer and/or a buffer layer. Upon provision of an electric potential above a threshold, electrons and holes may be injected into the electrochromic material and blocked by the insulating layer, resulting in an accumulation of the electrons and holes in their respective electrochromic material resulting in a change to the one or more optical properties of the electrochromic material. An opposite electric potential may be provided to reverse the change in the one or more optical properties.
