Abstract

Au:TiO 2 multilayer composite films were prepared by the method of alternating multitarget magnetron sputtering technique. Samples were annealed afterwards. The surface plasmon resonances of the annealed films are around 700nm. TEM pictures showed the remained layered structure with grown gold particles between the layers. The values of χ(3) measured by degenerated four wave mixing (DFWM) are in the order of 10-7 esu which are one order larger than the previous work. The figure of merit (FOM), χ(3)/α, is in the order of 10-12 esu cm. The great improvement of χ(3) is assumed to be the result from the enhancement of field localization caused by the metallic/dielectric host multilayer structure.
