We study the effect of adsorption rate on the particle size distribution in solution
grown ternary Pb1-xFexS nanoparticle films. Computer simulations of a model
incorporating adsorption and mass dependent diffusion have been performed in an
attempt towards understand the underlying dynamics of particle growth. A scaling of the
particle size distributions for different adsorption rates is observed in experimental as
well as numerical data. A TEM analysis of Pb 1-xFexS nanoparticle films reveals self
similarity in the particle size distributions corresponding to different adsorption rates as
a manifestation of the observed scaling.
