Synthesis of Cu2ZnSnSe4 Nanoparticles via Solvothermal Route

Abstract

Solvothermal synthesis was investigated as a viable method for the fabrication of quaternary Cu 2 ZnSnSe 4 (CZTSe) semiconductor compound. With metal salts and selenium powder as starting materials, single-phase CZTSe nanoparticles, as determined by X-ray diffraction and Raman analysis, were obtained in a quantitative yield after solvothermal reaction at 200°C for 24 h. Transmission electron microscopy (TEM) further revealed that the CZTSe were nanoflakes formed by aggregation of nanoparticles. The average particle size estimated from X-ray diffraction data was 49 nm. Furthermore, the metal ratio of CZTSe was precisely tunable by varying the molar ratio of starting metal salts in the solvothermal synthesis.

Recent advances in hydrothermally and solvothermally grown Co3O4nanostructures for electrochemical energy storage (EES) applications: a brief review

“…126 Mineralizers and additives are inorganic or organic substances, wherein mineralizers (used in high concentrations) are advantageous in controlling the pH of the solution, while additives (in relatively low concentrations) assist in dispersing particles or controlling crystal morphology. 55 Mineralizing agents function to accelerate both crystal growth and nucleation processes. 127 Various mineralizing agents such as NaOH, HMT, and urea are often used.…”

“…An appropriate choice of solvent is based on its density, melting point, boiling point, solvent polarity (a key parameter as it describes the interaction between solvent and solute), etc. 54,55 Hydrothermal/solvothermal techniques are extremely effective approaches for crystal growth and the development of almost all inorganic crystals. Significantly, the starting material used in these methods should be homogeneous, pure, and as fine as possible.…”
