Method of preparing Nanotube barcode coded by quantum dots

摘要

PURPOSE: A method for manufacturing a quantum dot-nanotube bar code is provided to enable infinite optical coding of a bar code by repetitively laminating quantum dot layers irradiating different color lights. CONSTITUTION: A method for manufacturing a quantum dot-nanotube bar code comprises the steps of: forming a nanotube in a plurality of pores formed on an anodized aluminum template; surface-treating the inside of the nanotube with a silane modifier; dipping the anodized aluminum template in the solution in which the quantum dot is dispersed, drying it, and laminating quantum dot layers(20,30,40,50,60) inside the nanotube; forming a separation layer(70) on the quantum dot layer; and repetitively performing third and fourth steps.
