Electroluminescent Device, Fabrication Method, and Light-Emitting Method for Realizing Multi-Color and White-Color Emission

摘要

cyan and red light light-emitting electroluminescent device of the possible number of colors, using a method of manufacturing the same, and this multi- proposes a method and a white light emitting color light emitting method. ; electroluminescent device of the present invention has at least one or more nano-materials and at least a combination of one or more polymeric or low-molecular light emitting material structure, such a light emitting device is preparing a nano-material, the method comprising dissolving the polymer or a low-molecular light emitting material, by using a nano-material that combine to form a nano-material suspension, polymer or low-molecular light emitting material and the nanomaterial solution comprising dissolved and suspended solids, the substrate produced through the step of fixing the nano-materials and polymers or low-molecular light emitting material is bonded to the solid solution phase and the substrate for applying the combination of the nanomaterial suspended in the polymer or low-molecular light emitting material, and a multi-color light emitting method using the same are the and a step of applying a voltage (V2) for the emission of a second color, such as applying voltage (V1) for emitting a first color of the multi-color light emitting device fabricated through a manufacturing method and a multi-color . In addition, a white light emitting method using the same, the voltage of the multi-color light emitting method in the electroluminescent device produced through the production process, such as the V1, and a step of repeating the V2 applied continuously. ; This invention According to the cyan light emission and red light emission or the like can be implemented by using a single light emitting device to emit light of various wavelengths, as well as such a light emitting element by applying voltage to the selection of a multi-color light emission is possible and also, light emission of each color The white light can be obtained continuously by repeating the on / off by a residual image effect.
