Method for obtaining zinc sulfide nanoparticles, “quantum dots,” in an ionic liquid, N-decylpyridinium tetrafluoroborate, is suggested. The average size and shape of the nanoparticles were determined by UV spectroscopy, dynamic light-scattering method, and scanning probe microscopy. It is shown that a high threshold concentration of nanoparticles is reached in the ionic liquid, and raising the concentration of precursors in the reaction mixture leads to an increase in the average size of nanoparticles. It is found that ultrasonic treatment affects the nanoparticle size.
