Abstract
Small colloidal HgI2, PbI2 and AgI particles (with particle diameters in the range 20–50 Å), were prepared in water and acetonitrile, and optical effects due to size quantization were observed. A simple method for the preparation of colloids was used to avoid the possibility of the formation of complexes or other conflicting absorbing species in solution. Colloids of HgI2 were prepared by simple agglomeration of HgI2 monomeric molecules. The PbI2 colloid formation in the solution of crystalline powder dissolved in acetonitrile was studied as well. Small colloids of AgI were prepared by reaction of silver salt with iodide in stochiometric ratio. AgI colloids were also incorporated in transparent silicate glass. Electron transfer reactions from electron donors to AgI particles in aqueous solutions were studied by pulse radiolysis technique.
