“…The morphology obtained from this study is reasonably similar to that of our recently reported iron sulfide thin films deposited using iron thiobiuret and diethyldithiocarbamate complexes. 21,27 EDX spectroscopy on five different areas of the films showed that the compositions are slightly sulfur deficient, a trend that increased at an elevated temperature ( Table 2).…”

“…The morphology, particle size and crystal-structure of the films deposited by this route can be closely controlled by the choice of a suitable solvent, deposition temperature and the nature of the precursor. We have been using single source precursors for metal chalcogenide thin films or nanoparticles and recently used complexes such as dithiocarbamates, [21][22][23][24] thiosemicarbazone 25 and thiobiurets 26 for the preparation of Fe-S thin films by AACVD.…”

Tris-(piperidinedithiocarbamato)iron(III) (1) and tris-(tetrahydroquinolinedithiocarbamato)iron(iii) (2) complexes have been synthesized and their single-crystal X-ray structures were determined. Thermogravimetric analysis (TGA) of the complexes showed decomposition to iron sulfide. Both complexes were then used as single-source precursors for the deposition of iron sulfide thin films by aerosol-assisted chemical vapour deposition (AACVD). Energy-dispersive X-ray (EDX) spectroscopy confirmed the formation of iron sulfide films. The addition of tert-butyl thiol almost doubled the sulfur content in the deposited films. Scanning electron microscopy (SEM) images of the iron sulfide films from both complexes showed flakes/leaves/sheets, spherical granules and nanofibres. The sizes and shapes of these crystallites depended on the nature of the precursor, temperature, solvent and the amount of tert-butyl thiol used. The observed optical properties are dependent upon the variation of reaction parameters such as temperature and solvent. Powder X-ray diffraction (p-XRD) studies revealed that pyrrhotite, hexagonal (Fe0.975S), marcasite and smythite (Fe3S4) phases were differently deposited.

“…Many deposition techniques have been employed to deposit thin films of metal sulfides including metal organic chemical vapor deposition (MOCVD) [9], aerosol assisted chemical vapor deposition (AACVD) [10,11], chemical precipitation [12], plasma source ion sulfuration [7], thermal spray [13], electro-deposition [8,14], hydrothermal method [5], sputtering [15,16] and chemical bath deposition (CBD) [17]. The last of these methods has, however, so far attracted considerable attention.…”

“…These phases of iron sulfide are: pyrite (cubic-FeS 2 ), marcasite (calcium chloride structure-FeS 2 ), pyrrhotite-IT (Fe 1-x S), pyrrhotite-4M (Fe 7 S 8 ), Fe 9 S 10 , greigite (cubic spinel-Fe 3 S 4 ), troilite-2H (FeS) and mackinawite (Fe 1 þ x S). The deposition of monophasic iron sulfide by any of the deposition technique is still a challenge due to the diversity in its structure [10]. Among different phases of iron sulfide, FeS is the one studied least since pyrite phase (FeS 2 ) has got much research interest.…”

a b s t r a c tThe growth of monophasic iron sulfide thin films onto glass substrates has been achieved by chemical bath deposition at acidic values of pH. Powder X-ray diffraction (p-XRD) confirms the deposition of tetragonal FeS (mackinawite) with preferred orientation along (001) plane. The crystallite size estimated by Scherrer equation was found to be 14 nm. Scanning electron microscopy (SEM) shows the formation of nanoflakes as base layer and nanoflowers as top layer. Energy Dispersive X-ray (EDX) analysis of the deposited iron sulfide thin films shows the iron to sulfur ratio close to 1:1 confirming the deposition of FeS. UV-vis absorption spectroscopy showed a blueshift due to the nanosize crystallites FeS with a band gap of 1.87 eV.

“…[13] Mixtures of pyrite/marcasite and pyrite/pyrrhotite films have been produced using unsymmetrical and symmetrical iron(III) complexes of dialkyl dithiocarbamates as single precursors by aerosol-assisted chemical vapor deposition method (AACVD). [14] Selective synthesis of troilite (FeS) and pyrite (FeS 2 ) has been achieved by a hydrothermal treatment of iron foils and sulfur powder in the presence or absence of hydrazine. [15] Pure troilite (FeS) as well as mixtures of troilite/pyrrhotite and troilite/pyrite films can be produced from the thermal decomposition of iron thiobiurets by an AACVD method.…”

2015): Synthesis of iron sulfide films through solid-gas reaction of iron with diethyl disulfide, Journal of Sulfur Chemistry, Iron sulfide films were synthesized by the solid-gas reaction of diethyl disulfide on iron foils in the temperature range of 658-768 K using a microbalance, where the film growth kinetics followed Deal-Grove behavior. Analysis of the films by X-ray photoelectron and Raman spectroscopies as well as X-ray diffraction and scanning electron microscopy analysis revealed the formation of combined FeS/FeS 2 (troilite/pyrite) films with a sheet-like morphology at low temperatures and only FeS (troilite) films with granular morphology at higher temperatures.
