A one-pot method was used to synthesize CuInxGa1–xS2 nanoparticles by substituting In3+ with Ga3+. The samples with composition of gallium ranging from 0% to 100% were synthesized by solving copper chloride, indium trichloride, gallium acetylacetonate, and thiourea as precursors in 1-octadecene, oleylamine, and oleic acid as noncoordinating, coordinating, and capping agent solvents, respectively. Depending on the chemical composition and synthesis conditions, the morphology of the as-synthesized nanoparticles obtained was trigonal, semitrigonal, hexagonal, and quasi-spherical. X-ray photoelectron spectroscopy and X-ray diffraction confirmed that Ga3+ substituted In3+ without any segregation over a wide range. The as-synthesized CuInxGa1–xS2 nanoparticles showed narrow size distribution across the entire composition range (x = 0–1) and band gap tuned in the range from 1.44 to 2.28 eV. The morphology, structure, and optical properties of the synthesized nanoparticles were characterized using transmission el...
