摘要：

Recently, silver nanoparticles (10-15 nm) embedded into silica thin films have been obtained in our laboratory by in situ reduction of a suitable silver organometallic compound (precursor) dissolved in a spin-on-glass (SOG) solution and subsequently span onto a substrate. Here, we present a study of the spatial distribution of these nanoparticles as a function of deposition and post-deposition parameters by using atomic force microscopy (AFM). We find that the distribution of the Ag particles is strongly dependent on the aging of the precursor-polymer blend obtained after the spin coating procedure, giving a uniform spatial distribution only with thermal annealing performed after several hours from the organometallic-polymer blend deposition.
