(a) Absorption spectra of ZnS nanoparticles in 1.5 mM aqueous CTAB as a function of time. [ZnS] = 5 × 10−4 M. Magnified view of absorption shoulder is shown as insert. (b) UV-absorbance at 294 nm of ZnS nanoparticles (concentration: 0.5 mM) as a function of time in spectrophotometer for three different CTAB concentrations
