Article Synopsis
  • - We investigated the properties of ZnS nanowires and nanorods that are capped with surfactants, focusing on their behavior in organic suspensions and how their photoluminescence changes with concentration and washing cycles.
  • - Photoluminescence emissions increased when the concentration of nanoparticles decreased, suggesting that the arrangement of nanostructures plays a significant role in their light-emitting behavior.
  • - Techniques like synchrotron small angle X-ray scattering revealed complex liquid-crystal-like structures in the nanoparticles, with a hexagonal structure for nanowires and a more intricate arrangement for nanorods, indicating optimal photoluminescence relies on a specific amount of surfactant on their surface.
