Abstract
Methods for producing nanoparticle thin films are disclosed. According to one of the methods, a nanoparticle thin film is produced by modifying the surface of nanoparticles to allow the nanoparticles to be charged, controlling an electrostatic attractive force between the charged nanoparticles and a substrate and a repulsive force between the individual nanoparticles by a variation in pH to control the number density of the nanoparticles arranged on the substrate.
