Growth of Bismuth Sulfide Nanowire Using Bismuth Trisxanthate Single Source Precursors

Abstract

Crystalline Bi 2 S 3 nanorods, nanotapes, and nanocrystals were obtained from the solvent thermalysis of bismuth trisxanthate precursors and related bismuth dithiocarbamate species in ethylene glycol at 197 °C. Precursors with different structural motifs were designed to produce compounds with different thermal decomposition temparatures, i.e., the dimeric motif of Bi(S 2 COR) 3 when R ) methyl and ethyl was found to have a lower decomposition temperature compared to precursors adopting the polymeric structure, so that solvothermalysis of the former gave rise to short nanocrystals; while in the case of the latter, long nanofibers were produced instead. Chemical vapor deposition on silicon substrates yielded well-defined nanorods of various lengths and diameters for almost all precursors. Internal microstructure of the nanorods was studied by high-resolution transmission electron microscopy.

Bismuth(III) Complexes with Bis(dimethylphenyl) Dithiophosphates: Synthesis, Characterization and Crystal Structure of [{(3,5-CH3)2C6H3O}2PS2]3Bi

“…Due to three short and three long Bi-S bond, the configuration is approximately C 3v . These ranges are consistent with typical values reported for the short and long ligand bond in [Bi{S 2 P(OC 6 H 4 Me-m) 2 . Asymmetrical coordination necessarily leads to an inverse relationship between the Bi-S and related P-S bond lengths.…”

“…[1][2][3][4][5][6][7][8] Low lability 9 and greater thermodynamic stability 10,11 of Bi-S compounds as compared to Bi-O compounds has resulted into their wide applicability in medicine and biology. 12,13 Due to its non-toxic and non-carcinogenic nature, the use of bismuth compounds in medicine can be traced back to the middle ages, 14 although less consideration has been paid to bismuth chemistry in comparison with that of rest of the members of group 15 elements.…”

AbstractThis work presents four complexes with general formula [{(ArO) 2 PS 2 } 3 Bi] (1-4), where Ar = 2,4-(CH 3 ) 2 C 6 H 3 , 2,5-(CH 3 ) 2 C 6 H 3 , 3,4-(CH 3 ) 2 C 6 H 3 and 3,5-(CH 3 ) 2 (4) has been determined by X-ray crystallography. The compound crystallizes in monoclinic P2 1 /c space group and Bi(III) centre is surrounded by six sulfur atoms from three symmetrically chelating bidentate diphenyl dithiophosphate ligands in a distorted octahedron environment.

Synthesis and structural characterization of new dithiocarbamate complexes from Sb(III) and Bi(III)

“…All synthesized complexes showed thioureide band ν(C N) in 1450-1550 cm -1 range and ν(C S) band in 950-1050 cm -1 [6] and proved the presence of dithiocarbamate moeity [7][8]. However, there are no significant differences between peaks shown.…”

Oriented Growth of Single‐Crystalline Bi2S3 Nanowire Arrays

“…[5,14,16,18,23] Bi 2 S 3 , an ionic n-type semiconductor with a direct bandgap of 1.3 eV, has numerous potential applications as a material for photovoltaic [24,25] and thermoelectric [26] devices. Several techniques have previously been reported for synthesizing randomly oriented Bi 2 S 3 nanowires including solvothermal and hydrothermal decomposition, [27][28][29] microwave irradiation, [30] crystallization of amorphous colloids, [31] chemical vapour deposition, [32] sonochemical, [33] solventless, [34] and ionic liquid-assisted methods. [35] Polycrystalline Bi 2 S 3 nanowires embedded inside the channels of AAMs have also been reported by electrochemical deposition [20] and photochemical synthesis.…”
