Abstract:	Au and Ag nanometer-size particle-doped alumina films were prepared by the aqueous sol–gel method. Their XPS and third-order nonlinear optical properties were examined. The XPS results gave evidence of an interaction between Au and alumina. Third-order susceptibilities, χ⁽³⁾ and χ⁽³⁾/ obtained by degenerate four-wave mixing method were in the order of 10^?8 esu and 10^?10 esu.cm for doped films, respectively.

Keywords:	Nonlinear optics Alumina Nanometer-size particle Noble metal
