    Abstract: Provided are an organic light emitting device (OLED) comprising: a first electrode; a second electrode; a hole injection layer (HIL), a hole transporting layer (HTL), and an emitting layer sequentially formed between the first electrode and the second electrode, wherein the work function, the IP or the absolute value of the highest occupied molecular orbital (HOMO) level of the HIL is greater than or equal to the absolute value of HOMO level of the HTL. In the OLED, the energy relationships between organic layers are controlled to facilitate hole injection and optimize the charge balance. Thus the efficiency of the OLED improves and the lifetime of the OLED increases.

    Abstract: Disclosed herein is a method for forming a metal pattern by using metal nanocrystals. The method comprises the steps of: (i) coating a photosensitive compound having a substituent, which is converted into a free carboxyl group by light exposure, on a substrate to form a photosensitive film; (ii) selectively exposing the photosensitive film to light in the presence of a photoacid generator to form a latent pattern for crystal growth having a free carboxyl group; and (iii) treating the latent pattern for crystal growth with a nanometallic solution in which metal nanocrystals can be formed to grow the metal nanocrystals on the latent pattern. According to the method, a metal wiring pattern can be formed in a cost-effective and relatively simple manner. Further, the metal pattern formed by the method can be useful in the manufacture of an electromagnetic interference filter for flat panel display devices or an electrode, and can thus be applied to devices, e.g., organic light-emitting devices (OLED) and organic thin-film transistors (OTFT).

    Abstract: The present invention relates to an organic luminescent material/clay nanocomposite with improved luminescent efficiency and stability, which is prepared by blending an organic luminescent material with a nanoclay, and an electroluminescent device employing the same. The electroluminescent device of the invention comprises: a transparent substrate; a semitransparent electrode deposited on the transparent substrate; a clay nanocomposite emissive layer spin-coated with an organic EL material/clay nanocomposite, positioned on the semitransparent electrode; and, a metal electrode deposited on the clay nanocomposite emissive layer. Since the electroluminescent device of the invention provides improved luminescent efficiency and stability, it can be practically applied to the development of organic semi-conductor.

    Abstract: The present invention provides ionomer-type emissive polymer whose heat-stability is improved by the formation of ionic cross-link, and electroluminescent device employing the same as an emissive layer. The ionomer-type emissive polymer is characterized by an ionomeric conformation, which has a backbone in a conjugate, non-conjugate or conjugate/non-conjugate multi-block conformation with or without a side chain in a conjugate or non-conjugate conformation, and 0.1 to 15% (mol/mol) of ions bound to the backbone or side chain of the emissive polymer with or without linker. The electroluminescent diode employing ionomer-type emissive polymer can be applied to the preparation of long-life and electricity-saving electroluminescent display device since it can luminesce at low voltage due to its ionomeric conformation and have higher heat-stability than the conventional ones.

    Abstract: A semiconductor memory device includes a plurality of memory cells each having a single transistor and a single capacitor on a semiconductor substrate. The capacitor has a storage electrode with an externally communicated box-type tunnel in its center, one portion of the storage electrode being connected to the source region of the transistor. A method for manufacturing the semiconductor memory device is also provided. Thus, storage capacity is raised by increasing the effective area of the capacitor, and the planarizing effect is also excellent.
