Synthesis and Spectral-Luminescent Properties of Zinc Sulfide Nanoparticles in a Perfluorosulfonic Membrane

Abstract

Zinc sulfide nanoparticles were synthesized in pores of a perfluorosulfonic membrane by ion exchange fixation of Zn²⁺ cations followed by the processing with gaseous hydrogen sulfide. Resulting ZnS particles are X-ray amorphous, have a low density, and are clearly expressed in absorption and luminescence spectra. Features of the nanoparticles optical properties were considered in light of electrons photoexcitation on antibonding orbitals (Zn–S)*.
