Synthesis and characterization of Cu2S nanostructures via cyclic microwave radiation

Disorder and variable-range hopping conductivity in Cu2ZnSnS4 thin films prepared by flash evaporation and post-thermal treatment

“…respectively [19]. Here, m  0.47 m 0 is the mean hole mass of CZTS [21,26], E 0 is the energy of the DOS peak in the AB (see Fig.…”

“…CZTS thin films were deposited by flash evaporation of ZnS, CuS and SnS binary compounds in powder form onto glass substrates at a nominal substrate temperature of 100º C. Salavati-Niasari et al have synthesized ZnS [17], SnS [18] and Cu 2 S [19] nanostructures by chemical methods. In our case, and considering these previous works, CuS and SnS powders were synthesized in an evacuated quartz ampoule from the pure elemental constituents, while commercially available ZnS was used.…”

Cube‐in‐Cube Hollow Cu9S5 Nanostructures with Enhanced Photocatalytic Activities in Solar H2 Evolution

“…According to the calculation of peak areas, the ratio of Cu/S is approximately 1.8:1, which matches well with the stoichiometric ratio of Cu 9 S 5. 19 The above analysis indicates that pure Cu 9 S 5 is successfully synthesized.…”

Synthesis and characterization of CuInS2 quantum dot in the presence of novel precursors and its application in dyes solar cells

“…1c and d, respectively. The absorption bands at 3434 and 1622 cm À 1 could be attributed to the & (OH) stretching and bending vibrations, respectively. Moreover, the absorption peak at 503 cm À 1 is due to Cu-O bond [4]. Furthermore, the absorption peak at 1334 cm À 1 corresponds to -COOH symmetry stretching vibrations, while absorptions at 2925 and 824 cm -1 are related to stretching and bending vibrations of C-H bond, respectively.…”
