Method of manufacturing metal nanowire and light-transmitting electrode and organic light-emitting device including metal nanowire manufactured thereby

A method of manufacturing a metal nanowire, comprising:

• preparing a reaction mixture by mixing a metal salt, a reducible solvent for reducing the metal salt into a metal, a capping agent for growing the metal into a wire, and a catalyst;
• and
• synthesizing a metal nanowire including a plurality of wire parts having different diameters in a single nanowire by reacting the reaction mixture at 1 to 5 atm in a reactor for 3 to 12 hours,
• wherein the synthesized metal nanowire includes a first wire part having a first diameter and a second wire part having a second diameter which is two times to fifteen times as great as the first diameter, and the second wire part is formed by increasing a diameter due to growth of side-surfaces while synthesizing the metal nanowire.
