Microwave-assistant route to hybrid semiconductor nanocrystals with quasi solution-solid-solid mechanism: Microwave-assistant route to hybrid semiconductor nanocrystals…
2014
A facile microwave-assistant route was developed for the synthesis of hybrid nanocrystals. Colloidal hybrid nanocrystals, Ag2S-CdS, were prepared by using Ag2S nanocrystals and cadmium diethyldithiocarbamate as raw materials under microwave irradiation. The fast ion conductor, Ag2S nanocrystal, catalyzes the growth of CdS nano-building blocks through a quasi solution-solid-solid mechanism. The ultraviolet-visible absorption and photoluminescence spectra of the Ag2S-CdS hybrid nanocrystals were investigated. One of the main advantages for this synthesis is the efficiency of dramatically reducing overall processing time. This report provides a new route for the growth of semiconductor hybrid nanocrystals based on Ag2S and may be extended to the preparation of other hybrid colloidal nanostructures.
