Chemical routes to chalcogenide materials as thin films or particles with critical dimensions with the order of nanometres

The deposition of thin films of cadmium zinc sulfide Cd1−x Zn x S at 250 °C from spin-coated xanthato complexes: a potential route to window layers for photovoltaic cells

“…Thin films and nanostructures properties are sensitive to the preparation method used and synthetic route [13][14][15]. Numerous techniques have been used to grow CdS and Cd 1-x Zn x S thin films including dip coating [16], electrodeposition [17], chemical vapor deposition (CVD) [18], aerosol-assisted CVD (AA-CVD) [19][20][21], chemical bath deposition (CBD) [2,8,22,23], spray pyrolysis [24,25], thermal evaporation [26], successive ionic layer and reaction (SILAR) [27], thermolysis [28,29], electrochemical atomic layer epitaxy (ECALE) [11], sol-gel spin coating, [30,31] doctor's blade, [32] and others [14,21,33,34].…”

Exploring the crystallization landscape of cadmium bis(N-hydroxyethyl, N-isopropyldithiocarbamate), Cd[S2CN(iPr)CH2CH2OH]2

“…When the solution is allowed to stand for another hour, the needles begin to dissolve and prisms emerge of the supramolecular isomer (SI), binuclear {Cd[S2CN(iPr)CH2CH2OH]2}2·2EtOH (2). These have been fully characterized spectroscopically and by X-ray crystallography.…”

“…(-6 -5 1), (12 -1 1), (-6 - 5 14) and (-2 6 1), again owing to poor agreement. For 4, the O2-hydroxyethyl residue, with the exception of the hydroxyl-H atom, was disordered over two positions in a ratio 0.851(2):0.149 (2). The ADP of matching pairs of atoms were constrained to be equal and nearly isotropic.…”

“…medicinal [1] and as single source precursors for nanoparticle generation of chalcogenides [2], complement well established uses, e.g. as lubricants, in the vulcanization of rubber, as flotation agents, etc.…”

Single-molecule precursor-based approaches to cobalt sulphide nanostructures

“…Nanoparticles of cobalt sulphide have been synthesized by hydrothermal (Liu 2005) or solvothermal methods (Qian et al 2000), microwave-assisted techniques (Chen et al 2003) and the thermolysis of single-source precursors (Dutta et al 2008;Maneerprakorn et al 2010). In our continuing search for routes to semiconductor nanoparticles from single-source precursors (Trindade et al 2001;Li et al 2006;Fan et al 2007;Afzaal et al 2010), we now report the synthesis of cobalt complexes of 1,1,5,5-tetramethyl-2,4-dithiobiuret, [Co{N(SCNMe 2 ) 2 } 3 ] (1), and 1,1,5,5-tetraisopropyl-2-thiobiuret, [Co{N(SOCN i Pr 2 ) 2 } 2 ] (2), and their use for the selective synthesis of Co 1−x S and Co 4 S 3 phase cobalt sulphide nanoparticles.…”
