Microwave-assisted synthesis of semiconductor nanoparticles in water/oil microemulsion

2005

Stable CdS and ZnS nanoparticles with exalted luminescence properties have been obtained in water/sodium bis (2-ethylhexyl) sulfosuccinate (AOT)/n-heptane microemulsion using microwave in order to take away selectively water molecules from microemulsion system. The nanoparticles synthesis was performed using a microwave exposure set-up opportunely assembled that allows irradiating the reactor with microwave of 2.45 GHz maintaining constant the temperature. The nanoparticles growth kinetics, as a function of irradiation time, was performed by means of UV-Vis spectroscopy. Information about the structural changes that microemulsion undergoes when irradiated with microwave was obtained by mean…
