“…These values are related to size-induced line broadening typical of nanocrystalline samples. Indeed, they compare well with other nanocrystalline synthetic tetragonal CTS samples [30,69,71] (See Table S3, Supporting Information File 1). Such width values impair the fit of other contributions in the Raman spectra, the details of which are presented in Table S3, Supporting Information File 1.…”

“…Hence, we can exclude that the short- and long-range disorder reckoned by both EXAFS and XRD lead to the increasing symmetry with respect to the natural counterparts ( I −42 m → F −43 m ) due to the complete mixing of Sn and Cu sites. The presence of associated phases such as SnS, Sn 2 S 3 and Cu 2 SnS 3 could be excluded (samples S1 and S3) [71]. The statistical analysis of the EMPA compositional data clearly showed that Zn is present only in sample S1, although this is very difficult to detect with EDX [45], and it confirmed that the composition of sample S3 is consistent with kuramite’s composition.…”

“…These values compare well with the difference expected from the peaks assigned to the structurally similar tetragonal kesterite [72] and stannite [75–76], suggesting that the main phase of these three samples is structurally related to the latter. In other studies, such difference have been assigned to tetragonal kuramite [70] or mohite [71]. The ratio between the areas of the first and second components is roughly 2.9(1), 1.35(7) and 1.38(7) for samples S1, S2 and S3, respectively: this points out that the main phases in samples S3 and S2 are very similar, and only a slight difference can be found for sample S1, which is consistent with the Raman spectra on the kesterite-type compounds [72–73].…”

The new generation of solar cells aims to overcome many of the issues created by silicon-based devices (e.g., decommissioning, flexibility and high-energy production costs). Due to the scarcity of the resources involved in the process and the need for the reduction of potential pollution, a greener approach to solar cell material production is required. Among others, the solvothermal approach for the synthesis of nanocrystalline Cu–Sn–S (CTS) materials fulfils all of these requirements. The material constraints must be considered, not only for the final product, but for the whole production process. Most works reporting the successful synthesis of CTS have employed surfactants, high pressure or noxious solvents. In this paper, we demonstrate the synthesis of nanocrystalline kuramite by means of a simpler, greener and scalable solvothermal synthesis. We exploited a multianalytical characterization approach (X-ray diffraction, extended X-ray absorption fine structure, field emission scanning electron microscopy, Raman spectroscopy and electronic microprobe analysis (EMPA)) to discriminate kuramite from other closely related polymorphs. Moreover, we confirmed the presence of structural defects due to a relevant antisite population.

“…The solid state approach via mechanochemistry can be realized through simple solvent-free technology. Moreover, the mechanochemical approach is reproducible, ensuring high yield, easy to operate and very important point is scale up, as was shown in several latest papers describing the preparation of similar materials in semi-industrial scale [35,36,37]. In the next part, the structural, surface and optical properties of mechanochemically synthesized CuInS 2 /ZnS nanocrystals are described.…”

In this study, CuInS2/ZnS nanocrystals were synthesized by a two-step mechanochemical synthesis for the first time. In the first step, tetragonal CuInS2 was prepared from copper, indium and sulphur precursors. The obtained CuInS2 was further co-milled with zinc acetate dihydrate and sodium sulphide nonahydrate as precursors for cubic ZnS. Structural characterization of the CuInS2/ZnS nanocrystals was performed by X-ray diffraction analysis, Raman spectroscopy and transmission electron microscopy. Specific surface area of the product (86 m2/g) was measured by low-temperature nitrogen adsorption method and zeta potential of the particles dispersed in water was calculated from measurements of their electrophoretic mobility. Optical properties of the nanocrystals were determined using photoluminescence emission spectroscopy.

“…Several metal selenides, together with binary and ternary copper sulfides were mechanochemically synthesized using a scalable eccentric vibratory mill, and in the case of CuS commercial production was also verified [ 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. Different types of mill, producing a different nature and intensity of mechanical energy, which is applied to the mechanochemical synthesis, can determine its course, and the formation of centers responsible for a solid-state reaction [ 33 ].…”

Copper(II) selenide, CuSe was prepared from Cu and Se powders in a stoichiometric ratio by a rapid, and convenient one-step mechanochemical synthesis, after 5 and 10 min of milling in a planetary, and an industrial vibratory, mill. The kinetics of the synthesis, and the structural, morphological, optical, and electrical properties of CuSe products prepared in the two types of mill were studied. Their crystal structure, physical properties, and morphology were characterized by X-ray diffraction, specific surface area measurements, particle size distribution, scanning, and transmission electron microscopy. The products crystallized in a hexagonal crystal structure. However, a small amount of orthorhombic phase was also identified. The scanning electron microscopy revealed that both products consist of agglomerated particles of irregular shape, forming clusters with a size ~50 mm. Transmission electron microscopy proved the nanocrystalline character of the CuSe particles. The optical properties were studied using UV–Vis and photoluminescence spectroscopy. The determined band gap energies of 1.6 and 1.8 eV for the planetary- and vibratory-milled product, respectively, were blue-shifted relative to the bulk CuSe. CuSe prepared in the vibratory mill had lower resistivity and higher conductivity, which corresponds to its larger crystallite size in comparison with CuSe prepared in the planetary mill.
