METHOD FOR PREPARING NANO RING ARRAY AND METAL NANOPARTICLE ARRAY

摘要

PURPOSE: A method for manufacturing a nano-ring array and a metal nano-particle array is provided to manufacture a single metal-based nano-particle array and a dual metal-based nano-particle array using a nano-ring array as a template. CONSTITUTION: A method for manufacturing a nano-ring array includes the following: A block copolymer solution containing a hydrophilic block and a hydrophobic block is applied on a substrate. The substrate is in contact with solvent vapor. The substrate is in contact with a solvent which selectively dissolves the hydrophilic block. A method for manufacturing a metal nano-particle array includes the following: The nano-ring array is manufactured. The nano-ring array is in contact with a metal precursor solution. One of ultraviolet ray irradiation, oxygen plasma treatment, and reducing agent treatment is implemented.
