Specific features of ZnCdS nanoparticles synthesized in different solvents

Resumo

Stable colloidal solutions of ZnCdS nanoparticles (3–6 nm in diameter) in polyvinyl alcohol, polyethylene glycol, and H₂O are produced. The size of the synthesized nanoparticles is independent of the relation between precursors. It is shown that stabilization of the particles is defined by the charge-stability factor and can be attained without any additional stabilizing additives. The ZnCdS quantum dots synthesized emit in a wide spectral range from 450 to 600 nm.
