The present invention relates to an optical film comprising a substrate on which an array of structures is formed, wherein a material having a different refractive index, absorbancy or reflectivity from that of a surface of the structures is partially coated on the surface of the structures, and a manufacturing method thereof. Specifically, the optical film according to one embodiment of the present invention may have a different transparency depending on the direction or can transmit light asymmetrically.

Provided are quantum dots having a gradual composition gradient shell structure which have an improved luminous efficiency and optical stability, and a method of manufacturing the quantum dots in a short amount of time at low cost. In the method, the quantum dots can be manufactured in a short amount of time at low cost using a reactivity difference between semiconductor precursors, unlike in uneconomical and inefficient conventional methods where shells are formed after forming cores and performing cleaning and redispersion processes. Also, formation of the cores is followed by formation of shells having a composition gradient.

Quantum dots having composition gradient shell structure and manufacturing method thereof

Provided are a nitride thin film structure and a method of forming the same. If a nitride thin film is formed on a substrate that is not a nitride, many defects are generated by a difference in lattice constants between the substrate and the nitride thin film. Also, there is a problem of warping the substrate by a difference in thermal expansion coefficients between the substrate and the nitride thin film. In order to solve the problems, the present invention suggests a thin film structure in which after coating hollow particles, i.e. hollow structures on the substrate, the nitride thin film is grown thereon and the method of forming the thin film structure. According to the present invention, since an epitaxial lateral overgrowth (ELO) effect can be obtained by the hollow structures, high-quality nitride thin film can be formed. Since a refractive index in the thin film structure is adjusted, there is an effect of increasing light extraction efficiency during manufacturing the thin film structure into a light emitting device such as a light emitting diode (LED). Also, when thermal expansion coefficient of the substrate is greater than that of the nitride thin film, total stress of the nitride thin film is decreased according to the compression of the hollow structures in the nitride thin film such that there is also an effect of preventing warpage of the substrate.

Structure of thin nitride film and formation method thereof

The present invention relates to a facilitated transport membrane for separation of alkene hydrocarbons from hydrocarbon mixtures, comprising a porous support and a solid polymer electrolyte consisting of a transition metal salt and a polymer having phthalic structure, in which the electrolyte is in solid state at its operating temperature. The facilitated transport membrane is prepared by forming a solid polymer electrolyte consisting of a transition metal salt and a polymer on a porous support. The transition metal salt can selectively and reversibly form a complex with alkene hydrocarbons and the polymer can dissociate the transition metal salt. In particular, the polymer matrix allows the transition metal salt to be well dissociated because it has a phthalic structure capable of being coordinated to a transition metal ion.
