Size and Shape Control of Colloidally Synthesized IV-VI Nanoparticulate Tin(II) Sulfide

We report the synthesis and characterization of monodisperse SnS nanocrystals and demonstrate shape control by varying the ratio of ligands present in the reaction mixture. The nanoparticles are subsequently linked to conducting transparent substrates, and their optoelectronic response is probed. Values of the photocurrent for this system, without attempts to optimize, in the range of 6-8 nA cm(-2) were obtained.
