Fabrication of thin film Ag/CuCl layered quantum dot composites using solid state diffusion

Nanoscale semiconductor materials, often referred to as clusters of quantum dots, were intensified mainly for their interesting non-linear optical properties. Materials with a relatively small exciton Bohr radius such as CuCl are of interest because of the predicted mesoscopic enhancement of the excitonic optical non-linearity. The maximum third order susceptibility of CuCl crystalline doped glasses were reported to be 2x10 super(-8) esu. CuCl nanocrystallites in a glass matrix were first fabricated by a striking or a heat-treatment process. The preparation of Ag/CuCl layered nanoparticles in a glass matrix by solid state diffusion is presented.
