Phase-controlled synthesis of ZnS nanocrystallites by mild solvothermal decomposition of an air-stable single-source molecular precursor

Optimization of the recipe for the synthesis of CuInS2/ZnS nanocrystals supported by mechanistic considerations

“…The CIS/ZnS QDs used for this analysis were synthesized according to the recipe described in the experimental section, but ZDC was used as a starting material for zinc and sulfur. Because ZDC can decompose at comparable low temperature (at above 150°C) [50], the interdiffusion of core and shell should not occur at such low temperature. Figure 7 shows that at the beginning of shell growth the PL emission wavelength undergoes a dramatic blue-shift.…”

Hydrothermal technology for nanotechnology

“…Zhang et al have prepared ZnS nanocrystallites through mild hydrothermal decomposition [100]. The use of zinc acetate and sodium diethyldithiocarbamite with an experimental temperature of 150e200 C for 12e72 h produces ZnS nanocrystallites with a different morphology.…”

Zinc blende versus wurtzite ZnS nanoparticles: control of the phase and optical properties by tetrabutylammonium hydroxide

“…[1][2][3][4][5] The synthesis of ZnS nanocrystals with tunable size and phase not only provides alternative variables in tailoring the physical properties of this semiconductor material, but is also vital to develop them as building blocks in constructing the future nanoscale optoelectronic devices using the so-called ''bottom-up'' approach whereby atoms and molecules selforganize into nano-sized crystals or more complex molecular assemblies. 6,7 ZnS can adopt three phases: cubic zinc blende, hexagonal wurtzite or the rarely observed cubic rock salt. 8 The cubic zinc blende structure of ZnS is the most stable form in the bulk which transforms into a hexagonal wurtzite structure at 1020 1C and melts at 1650 1C and both ZnS polymorphs have industrial applications.…”
