The aim of this work was to establish the average size of silver halide nanosols. The method applied was based on the optical turbidance measurements in real time of crystallization process. Dilute turbid suspensions of silver bromide, chloride and iodide stabilized by excess of halide ions and gelatin were measured over wavelength range from 450 nm to 600 nm. Experimental results were compared with the scattering theory of Rayleigh. Relation between dosing rate of reactants to dispersion system and size of obtained silver halide crystals was investigated. Interest in crystalline gelatine-stabilised aqueous suspensions of silver halide is due to their application as a substrate for the synthesis of silver nanoparticles.
