Abstract

Zinc sulfide nanoparticles (quantum dots) were synthesized from aqueous solutions of sodium sulfide and zinc sulfate using pyridinium ionic liquids. The average sizes of zinc sulfide nanoparticles were determined by UV spectroscopy, X-ray diffraction, probe and scanning electron microscopy. The influence of the structure and concentration of pyridinium ionic liquids with the tetrafluoroborate anion of the same name on the size of zinc sulfide nanoparticles has been studied. The effect of the precursor concentration on the size of the nanoparticles formed in the ash was established.
