In this work, copper antimony sulphide (CuSbS 2 ) particles were synthesised by a microwave irradiation method. The effects of Cu/Sb ratio in the precursor solution and microwave irradiation power on properties of CuSbS 2 particles were investigated by X‐ray diffraction, X‐ray photoelectron spectroscopy, and scanning electron microscopy. The results showed that the sphere‐like CuSbS 2 particles with single phase and stoichiometric composition was synthesised at 400 W for 4 min first and then 240 W for 6 min, when the ratio of Cu/Sb was 1:2. The formation mechanism of CuSbS 2 particles was also investigated through evaluation of as‐prepared particles with different reaction time.
