CONSTITUTION: A photosensitivity quantum dot comprises a quantum dot and plural photosensitive moieties which is bound to the surface of the quantum dot and contains Si and photosensitive functional group. The photosensitive moieties have chemical formula 1 or 2. A composition for forming quantum dot-containing pattern contains the photosensitive quantum dot, photoinitiator, and solvent. A method for forming the quantum dot-containing pattern comprises: a step of preparing the composition for forming quantum dot-containing pattern; a step of providing a quantum dot-containing film; a step of selectively exposing the film to the light; and a step of developing the film.
Abstract:
PURPOSE: A radical polymerization composition and a pattern formation method using thereof are provided to simply and easily control the size of a pattern by adjusting components of the composition. CONSTITUTION: A radical polymerization composition contains a photosensitive material, a photo initiator, a solvent, and a pattern size controlling material. The pattern size controlling material is selected from the group consisting of a polymer-containing radical scavenger, and a photo sensitizer. A polymer from the polymer-containing radical scavenger is selected from the group consisting of polystyrene, poly(methyl) methacrylate, polymethacrylate, poly acrylate, and polyacrylate. The radical polymerization composition additionally includes a quantum point or a two photon absorption material.
