| Popis: | CdS nanoparticles were prepared by reacting CdCl2 and Na2S in different microemulsions and several micellar media comprising combinations of ionic liquid, ionic, nonionic, zwitterionic amphiphiles, isopropyl alcohol, and isopropylmyristate as templates. This simple chemical method was found to be effective in the preparation of CdS dispersions mostly in the range of 3–8 nm with moderate polydispersity. The dispersions were characterized by taking UV–Vis and fluorescence spectra as well as by DLS, EDX, SEM, and TEM methods. Globular, sharp-edged elongated flake-like, and wire type morphologies were witnessed by SEM. TEM results evidenced spherical nanoentities. The dispersions witnessed both fairly and weakly semiconducting varieties; insulator-type dispersions were also observed. They have shown characteristic fluorescence properties. The nanodispersions evidenced biocidal activities toward both gram-positive and gram-negative bacteria. |
