Abstract:
PURPOSE: A method of forming an inorganic thin film and a sputtering system therefore are provided to effectively protect the organic layer of an organic electronic element since oxygen permeability and water permeability are too low compared with a thin film, which is synthesized from single inorganic material. CONSTITUTION: A sputtering system for forming an inorganic thin film comprises a vacuum chamber(10), magnetron deposition sources(11), a substrate holder(13) and a power supply unit. The inside of the vacuum chamber is maintained in a vacuum state. The magnetron deposition sources deposit an inorganic thin film. The magnetron holder is installed on a position facing at least one of the magnetron deposition sources and holds a substrate. The substrate forms an organic-polymer protecting layer by coating photo-curable polymer and curing the coated photo-curable polymer. The power supply unit applies RF power and frequency to each of the magnetron deposition sources.

Abstract:
A white and color photoexcitation light emitting sheet and a manufacturing method thereof are provided to obtain a white and color surface light source by controlling a composition ratio and a kind of light emitting material according to a light source having an ultraviolet wavelength or a blue wavelength. A white and color photoexcitation light emitting sheet includes a substrate(10), a light source, and a white and color photoexcitation light emitting layer(20). The light source is formed on the substrate. The light source is a lamp or a light emitting device including an organic light emitting device and an inorganic light emitting device. The organic light emitting device and the inorganic light emitting device emit a light of an ultraviolet wavelength or a blue wavelength. The white and color photoexcitation light emitting layer converts a light emitted in the light source into a light of a different wavelength. The white and color photoexcitation light emitting layer is made of mixture of white and color photoexcitation light emitting material, base polymer, and solvent.
