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

Abstract

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.

Tin sulfide (SnS) nanostructured films deposited by continuous spray pyrolysis (CoSP) technique for dye-sensitized solar cells applications

“…Synthesis of low cost, non-toxic, earth-abundant and environmental friendly NCs by simple methods are the focus of recent research works [3]. SnS is abundant and cheap material, with no environment hazards, exhibits both p and n type behaviors [4] and has both direct (1.3 eV) and indirect (1.09 eV) band gaps [5]. Its layered structures, inert surface free of dangling bonds [6], less number of surface traps, perfect stoichiometry, excellent catalytic activity and good electrical conductivity [7] make it a potential candidate as a CE for DSSCs.…”

Solvothermal synthesis of nanostructured CuInS2 thin films on FTO substrates and their photoelectrochemical properties

“…All of these data confirm that the nanoworm electrode has much better photoelectric performance than the nanosheet electrode. It is well known that the difference in photocurrent intensity of the CIS thin films may be due to differences in stoichiometric compositions, defect density, or ascribe to the capacity of light-harvesting deriving from the differences in absorption [39]. Compared with the nanosheets, these nanoworms synthesized in sulfide-rich environment are of better crystalline which may be due to its improved film conductibility [19,21].…”

Quantum Dots: Synthesis and Characterization

“…Further, many smaller band-gap materials, such as InP [31], InAs [32], PbS [33], PbSe [34], PbTe [35], SnS [36], and SnTe [37] can be synthesized as colloidal solutions with narrow size distributions. Thus, all band-gap energies from the UV-Vis region down to the infrared (IR) region can be covered with colloidal nanocrystals today, all prepared with the hot-injection approach.…”
