Transmission electron micrograph of colloidal ZnS nanoparticles prepared in aqueous micellar solution of CTAB showing the effect of salt concentration at [CTAB] = 0.5 mM (a) [ZnS] = 0.3 mM; (b) [ZnS] = 0.5 mM. Inset shows higher magnification image. (c) Powdered ZnS nanoparticles redispersed in water. (d) An agglomerate of 8–10 particles and individual nanoparticle shown in inset (e,f) SEM images of ZnS nanoparticles at different magnifications
