A Large-Scale Synthesis and Characterization of Quaternary CuInxGa1−xS2 Chalcopyrite Nanoparticles via Microwave Batch Reactions

Table 1

Representative sample compositions (from ICP-OES analysis) from 10 of 29 highly cross-linked CuIn_0.7Ga_0.3S₂ nanoparticle batches prepared at 200°C. *The standard deviation of all samples is 0.89 for Cu, 0.96 for In, and 0.35 for Ga.
