Abstract	Quaternary Cu (CFTS) nanocrystals exhibiting a new wurtzite phase have been synthesized using a solution-based method. The optimum temperature to obtain phase-pure wurtzite CFTS is ∼210 °C. As the reaction temperature is increased from 210 °C to 310 °C, a mixture of wurtzite and zinc blende CFTS is obtained. The morphology of the as-synthesized wurtzite CFTS is oblate spheroids with an average size of 20nm. The corresponding band gaps of CFTS nanocrystals synthesized at different temperatures varies between 1.54 eV–1.49 eV. Based on the results, CFTS with optimal band gap, low-toxicity composition and earth-abundant elements appears attractive as a low-cost substitute for use in thin film solar cells.
