    摘要: A method and an apparatus have been developed to fabricate large area uniform silicon cone arrays using different kinds of ion-beam sputtering methods. The apparatus includes silicon substrate as the silicon source, and metal foils are used as catalyst. Methods of surface modification of the as-synthesized silicon cones for field emission application have also been developed, including hydrofluoric acid etching, annealing and low work-function metal coating. Nano-structure modification based on silicon cones takes advantage of the fact that the cone tip consists of metal/metal siliside, which can be used as catalyst and template for nanowires growth. A method and an apparatus have been developed to grow silicon oxide/silicon nanowires on tips of the silicon cones.

    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.
