Abstrakt

Nanoporous glass containing spherical or ellipsoidal nanovoids, respectively, has been produced by electric-field-assisted dissolution of Ag nanoparticles embedded in glass-metal nanocomposites. Small angle x-ray scattering before and after particle dissolution gives evidence that in the case of spherical nanoparticles the remaining nanovoids have the same size distribution (approximate to 20 nm average diameter) as the original silver particles. Spheroidal particles of uniform orientation leave strongly aspherical nanovoids, which undergo a slight shape relaxation from aspect ratio 4.7 (particles) to 3.8 (holes).
