✦ Synopsis

In this study the formation of approximately spherical assemblies of nanocrystalline primary particles of CdS in a CS 2 -waterethylenediamine (CWE) microemulsion induced by ultrasonic irradiation is described. CS 2 was employed as the sulfur source for CdS and also as the oil phase in the microemulsion. The particles were studied with X-ray powder diffraction, transmission electron microscopy, UV/Vis absorption spectroscopy, and photoluminescence spectroscopy. A blue shift compared to bulk CdS was observed in absorption and photoluminescence spectra.

The effect of surfactant type and temperature on the kinetics of the formation of platinum nanoparticles in water-in-oil microemulsions by chemical reduction of PtCl 2- 6 were examined with timeresolved UV-vis absorption spectroscopy. The surfactants used were poly(ethylene glycol)monododecyl ethers
