摘要
Metal nanocluster composite glass prepared by 200 keV Ag ions' implantation into silica with dose of 2 x 10(17) ions/cm(2) has been studied. The formation of sandwiched nanocluster-nanovoid-nanocluster structures has been evidenced by in situ transmission electron microscopy experiment (TEM). Fast nonlinear optical refraction and nonlinear optical absorption coefficients were measured at 532 nm and 1064 nm of wavelength by the Z-scan technique. The third-order nonlinear susceptibility chi((3)) of this kind of sample was determined to be 4.0 x 10(-8) esu at 532 nm and 9.0 x 10(-8) esu at 1064 nm, respectively. Published by Elsevier Ltd.
