Abstract

A process for producing an optical element having a gradient structure, wherein a potential difference is generated in a nanocomposite material comprising nanoscale particles in a matrix material to cause a directed diffusion of the nanoscale particles in the matrix material and a concentration gradient of the nanoscale particles in the matrix material.
