Abstract
Disclosed is a method for forming a metal particle layer having irregular structures in a simpler manner. The method includes bringing a base into contact with an activation solution including a metal compound, an organic acid activator, and a complexing agent. The base is oxidized by the organic acid activator to produce electrons and the metal compound is reduced by the electrons to deposit metal particles on the surface of the base. Also disclosed is a method for fabricating a light emitting device with improved light extraction efficiency that uses a metal particle layer formed by the above method.
