中文摘要 | Thin films of SrBi2Nb2O9 with and without the inclusion of Ag nanocrystals were prepared on MgO (001) substrates by alternative pulsed laser ablation of SrBi2Nb2O9) ceramic and Ag metal in a nitrogen atmosphere. The size of the Ag nanocrystals can be brought down to ca. 5.0 nm, as revealed by transmission electron microscopy and X-ray diffraction. We measured the third-order susceptibility chi((3)) of the deposits by single beam z-scan technique at a wavelength of 532 nm. It is found that SrBi2Nb2O9,) is an effectively nonlinear optical medium, exhibiting a very large chi((3)). With the inclusion of Ag nanocrystals the chi((3)) was nearly doubled (Re chi((3)) - 8.052 x 10(-7) esu, and Im chi((3)) = - 1.717 x 10(-7) esu), which comes very close to the maximum value available in the current time. This indicates that the Ag:SrBi2Nb2O9 composite structure can be an excellent candidate for nonlinear optical applications. A general approach for further enhanced third-order susceptibility by tailoring the dielectric constant of the metal inclusion is briefly discussed. (c) 2006 Elsevier B.V All rights reserved. |
