摘      要：Gold nanoparticle arrays fabricated via layerby-layer technique were investigated using grazing-incidence small-angle X-ray scattering(GISAXS) *** containing two gold nanoparticle layers that were separated by 5,11,15 and 21 poly electrolyte(PE) interlayers were *** using different X-ray incident angles,correlations of gold nanoparticles(GNPs) in the same layer and in two different layers were *** is found that both sideway correlations between GNPs in the same layer and vertical correlation between two gold nanoparticle layers depend on the thickness of PE *** to sideway correlation,the size of GNPs is determined to be(13.0±0.5) nm in all of the four samples,which was also proved by scanning electron microscopy(SEM) and theoretical calculation of form factor of spherical *** vertical correlation,distance between two gold nanoparticle layers was determined for sample with 11,15 and 21 PE *** distances can be reasonably explained with the number of PE layers and the thickness of single PE *** results indicate that by repeated depositing of oppositely charged PE layers,a true three-dimensional(3 D) nanostructure can eventually be designed.
