英文摘要: Abstract(#br)A sonochemical method was utilized to synthesize Cu(In x Ga 1-x )Se 2 (CIGSe) nanoparticles using NaBH 4 with ethanol as a solvent. The effect of the ultrasonification time intervals on the synthesis was investigated in the range of 2–5 h, 5 h was found to be the most suitable time to obtain the expected CuIn 0.7 Ga 0.3 Se 2 compounds. The as-synthesized CIGSe nanoparticles possessed a tetragonal structure with quasi-spherical shape, band gap of ∼1.25 eV, and targeted Cu(In x Ga 1-x )Se 2 composition. A new reaction scheme is proposed to explain the role of NaBH 4 in the plausible reaction paths. The non-toxic solvent used in the synthesis with no additional heating makes the developed method cheaper and “greener” than the previously reported methods.
