Abstract

We used diffusing wave spectroscopy to determine the phase diagrams of binary mixtures of charge-stabilized colloidal particles of different dimensions in the low-screening limit. As the ratio of radii r = r 1 / r 2 was increased progressively towards 1; the structure of the diagrams evolved from eutecticlike to azeotropiclike and finally to a diagram where complete solubility was found; much like in atomic systems. We present for the first time evidence for liquid-galss transitions in these strongly interacting systems as the relative composition of both species is varied.
