TL;DR: It is demonstrated that electron-transporting n-type hosts, which typically include an acceptor moiety in their chemical structure, have the intrinsic ability to balance the charge fluxes and broaden the recombination zone in delayed fluorescence organic electroluminescent devices, while at the same time preventing the formation of high-energy excitons.

TL;DR: A novel form of harmonious fusion among interface exciplex, UEML, and tandem structure is successfully realized, which sheds light on further development of ideal OLED structure with high efficiency, simplified fabrication, low power consumption, low cost, and improved color gamut, simultaneously.

TL;DR: In this paper, the authors demonstrated efficient all-inorganic perovskite LEDs (PeLEDs) via co-evaporation of cesium bromide (CsBr) and lead bromides (PbBr2) based on a vacuum thermal evaporation process.

TL;DR: In this paper, the inorganic and organic electron acceptors used as p-dopants in N,N′-di(naphthalene-1-yl)-N,N-diphenyl-benzidine (NPB) in organic light-emitting diodes (OLEDs) are carried out.

TL;DR: In this paper, an organic small molecular buffer layer, e.g., a 2-(diphenylphosphory) spirofluorene (SPPO1) layer, was inserted between PMMA and graphene, forming a PMMA/SPPO 1/graphene sandwich structure.
