STRUCTURAL AND OPTICAL CHARACTERISTICS OF CdxZn1–xS NANOPARTICLES STABILIZED IN AQUEOUS SOLUTIONS OF POLYMERS

The structural and optical characteristics of CdxZn1–xS nanoparticles, produced in aqueous solutions of sodium polyphosphate, polyvinyl alcohol, and gelatin, were studied. It was shown that the stoichiometric ratio of Cd(II) and Zn(II) in the nanoparticles can differ from that in the initial mixture. It was established that the main factors determining the final size of the CdxZn1–xS nanoparticles are the nature and concentration of the polymer, the ratio of the initial concentrations of the reagents, and the temperature and duration of the post-synthesis treatment of the colloids.
