Glass ceramics with nanosized crystallites shows an unexpected high transparency, which is not accounted for by the Rayleigh theory of light scattering. Simple analytic arguments ascribe this large transparency to large spatial correlations in the number distribution of the nanocrystallites. Introducing a two-dimensional lattice model that mimics the nucleation and the coarsening phenomena leading to their formation, we show that the extent of such correlations is determined by the spatially limited diffusion of the particles that form the crystallites.

Abstract
Glass ceramics with nanosized crystallites shows an unexpected high transparency, which is not accounted for by the Rayleigh theory of light scattering. Simple analytic arguments ascribe this large transparency to large spatial correlations in the number distribution of the nanocrystallites. Introducing a two-dimensional lattice model that mimics the nucleation and the coarsening phenomena leading to their formation, we show that the extent of such correlations is determined by the spatially limited diffusion of the particles that form the crystallites.File in questo prodotto:
