Opis:: The results of research into the preparation of silver nanoparticles using photoreduction in the presence of hydroquinone as the reductant were discussed. Substrates for the synthesis of silver nanoparticles were ultrafine crystalline gelatine-stabilised aqueous suspensions of silver bromide. The influence of the reductant to substrate molar ratio and the medium's pH to the efficient production of silver nanoparticles were studied. The properties of resultant silver particles were examined using UV-Vis spectroscopy. Transmission electron microscopy was used for the photomicrography of silver nanoparticles suspensions.

Opis:: 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.

Opis:: This paper present the results of studies on ultra fine-crystalline silver bromide suspensions, which were stabilized by gelatin and excess of bromide ions. Relation between dosing rate of reactants to size of obtained silver bromide crystals was investigated. Granulometric properties obtained nanocrystals were studied by turbidity method and by technique of Dynamic Light Scattering (DLS). Additionally, a photomicrograph of suspension using Scanning Electron Microscopy (SEM) was performed.
