    摘要： The present invention relates to an AC voltage-driven light emitting device having a single active layer of a core-shell structure (p-i-n structure) in which intrinsic semiconductor nanocrystals, exciton combination centers, are uniformly and isotropically distributed around p-type polymer particles, and n-type small molecular particles surround the semiconductor nanocrystals and p-type polymer, and a manufacturing method thereof. An active layer of a core-shell structure using a polymer-semiconductor nano hybrid in the light-emitting device has an inversion symmetry characteristic showing the same current-voltage characteristic during application of a voltage in a forward direction and a reverse direction. Therefore, due to this inversion symmetry characteristic, the light emitting can be driven by even an AC voltage. Also, since the device can be driven by an AC voltage, limitations of an existing DC voltage-driven organic light emitting diode, that is, destruction or a defect of the device by an overcurrent and generation of a dark spot by degradation of local constituent organic materials are solved.

    摘要： Disclosed are methods for preparing pure graphene using chemical bonding between graphite oxide and metal oxide nanoparticles, and graphene and nanoparticles having a quasi metal oxide-graphene core-shell prepared therefrom. The disclosed methods for preparing graphene allow chemical bonding and separation through a simple acid treatment process using inexpensive materials. Also, because the reaction can be carried out at low temperature, the processing cost is low. And, pure graphene with few impurities can be prepared quickly in large scale.
