    摘要: An electroluminescent element has an anode, a cathode, and an organic layer structure between the two electrodes. The layer structure has a luminescent zone containing 1,9-perinaphtylene-10-1′-naphthylanthracene or derivatives as dopant. The luminescent material utilized as dopant has the following structure called pNNA or pNNA derivatives: Wherein: R1, R2, R3, R4 are individual substituents or a group of substituents, and they may be identical or different. Each substituent is individually selected from the following groups consisting of: H, alkyl (—R), halogen (—X), aryl (—Ar), alkenyl (RCH═CH—), allyl(CH2═CHCH2—), cyano (NC—), isocyano (CN—), amino (H2N—), tertiary amino (R2N—or Ar1Ar2N—), amide (RCONR—), nitro (N2O—), acyl (RCO—), carboxyl (—CO2H), alkoxyl (RO—), alkylsulfonyl (RSO2—), hydroxy (HO—) and single or fused aromatic heterocyclic rings.

    摘要: A low-voltage organic light-emitting device has a light-transmissive hole-injecting electrode on a light-transmissive substrate, and formed over the hole-injecting electrode, in sequence, an organic hole-transporting layer, an organic light-emitting layer, a bi-layer interfacial structure, an electron-transporting layer having an electron affinity higher than an electron affinity of the light-emitting layer, and an electron-injecting electrode. The bi-layer interfacial structure provides effective electron transport from the electron-transporting layer to the light-emitting layer.

    摘要: An organic light-emitting device capable of reducing ambient-light reflection from a cathode includes a light-transmissive substrate, a light-transmissive anode, an organic hole-transporting layer, and an organic electron transporting layer. A reflection-reducing structure disposed between the electron-transporting layer and a light-reflective cathode is capable of providing electron injection into the electron-transporting layer and of substantially reducing reflection of ambient-light entering the device.

    摘要: Fluorination can be used to neutralize transition metal impurities in Si. Fluorine is incorporated into the near-surface region of Si by implantation or annealing in a fluorine containing ambient. Thermal treatments at appropriate temperatures are used to initiate the interdiffusion and reaction between fluorine and metal contaminants. The impurities readily react with fluorine to form a compound or complex, thus significantly reducing the number of mid-gap impurities.
