  • Patent number: 10818865
    Abstract: The present disclosure provides multilayered hole injection structures including one or more layers of oxides for application in an organic electroluminescent device. The layered structures include an insulating metal oxide such as Al2O3 including a transition metal oxide to lower the hole injection barrier and enable hole transfer which is sandwiched between the conductive aluminum layer and a hole transport layer. The layered structure may also include a tri-layered structure stacked sequentially including a first electrically conductive layer, an insulating metal oxide and a hole injection layer material selected from a group of transition metal oxides.

    Inventors: Jae Jin Lee, Zheng-Hong Lu
  • Publication number: 20200194691
    Abstract: An emissive zone for electroluminescent devices is provided, comprising of an emissive host with small singlet-triplet energy splitting and a triplet assistant dopant with HOMO and/or LUMO energy levels within the bandgap of the host material and triplet energy greater than that of the host. The purpose of the non-emissive dopant is two-fold; charge trapping and energy transfer to the host. With careful material selection, exciton formation on the dopant and subsequent energy transfer to the host allows for excitons to be funneled to the singlet-state of the host. Reduction of long-lived excitons consequently reduces undesirable excited state annihilation processes that lead to organic degradation.

  • Patent number: 9139917
    Abstract: A nanocomposite material that is both transparent and electrically conductive is provided. The nanocomposite comprises a nanoporous matrix, preferably formed from nanoparticles, that is internally coated with a transparent conductive material to define an internal conductive path within the nanocomposite. The nanocomposite is substantially transparent over a defined spectral range that preferably includes at least a portion of the visible spectrum, and preferably comprises pores with a mean diameter of less than approximately 25 nm. A bilayer may be formed by depositing a layer of a transparent conductive material on top of a nanocomposite layer, or by depositing a second layer of a nanocomposite having different optical properties. The nanocomposites formed using a combination of sequential and/or concurrent deposition techniques are correspondingly discrete and/or continuously varying structures.

  • Publication number: 20140326970
    Abstract: New carbazole-based compounds are provided that are useful as host materials for singlelayer and multilayer organic light-emitting diode (OLED) devices. Highly efficient single-layer OLEDs have been demonstrated using new N-heterocyclic carbazole-based host materials. Phosphorescent OLEDs with a structure of ITO/MoO3/host/host:dopant/host/Cs2CO3/Al have been fabricated in which the new host materials act simultaneously as electron-transport, holetransport and host layer. Using this design, devices with maximum current and external quantum efficiencies of 92.2 cd and 26.8% were achieved, the highest reported to date for a single-layer OLED.
