“…Feng and co-workers prepared thin films of (Zn,Fe)S (W) by MOCVD at 350 °C from [Fe(CO) 5 ], Me 2 Zn and H 2 S 32 and the same material was synthesised in nanoparticulate form upon solvothermal decomposition of [Zn(Aftscz) 2 ] and [Zn(AftsczH) 2 Cl 2 ] (AftsczH = monoacetylferrocene thiosemicarbazole) in ethylene glycol. 33 Nanoparticles of (Zn,Fe)S (S) have also been synthesised; Chen et al prepared Zn 0.9 Fe 0.1 S upon annealing nanoparticles produced from a micro-emulsion of [Fe(CO) 5 ], [Zn(O 2 CCH 3 ) 2 ] and CH 3 (CH 2 ) 11 OSO 3 Na (sodium dodecyl sulphate) in water with added thioacetamide. 34 …”

Despite the promising applications of copper selenide nanoparticles, an in-depth elucidation of the inherent properties of tetragonal Cu(2)Se (β-Cu(2)Se) has not been performed because of the lack of a facile synthesis on the nanoscale and an energy-intensive strategy is usually employed. In this work, a facile wet-chemical strategy, employing HCOOH as reducing agent, has been developed to access single-crystalline metastable β-Cu(2)Se hyperbranched architectures for the first time. The process avoids hazardous chemistry and high temperatures, and thus opens up a facile approach to the large-scale low-cost preparation of metastable β-Cu(2)Se hyperbranched architectures. A possible growth mechanism to explain the formation of the β-Cu(2)Se dendritic morphology has been proposed based on time-dependent shape evolution. Further investigations revealed that the metastable β-Cu(2)Se can convert into the thermodynamically more stable cubic α-Cu(2-x)Se maintaining the dendritic morphology. An increase in electrical conductivity and a tunable optical response were observed under ambient conditions. This behavior can be explained by the oxidation of the surface of the β-Cu(2)Se hyperbranched structures, ultimately leading to solid-state phase conversion from β-Cu(2)Se into superionic conductor α-Cu(1.8)Se, which has potential applications in energy-related devices and sensors.
