The atomic ratios of PbS QDs used in this work. Experimental data for the Pb-to-S ratio are obtained using WDS, and the I-to-Pb in TBAI-treated PbS QD thin films is measured using XPS. We include the ratios for the simulated QD used in DFT calculations for comparison.
| Samples | I/Pb ratio | Pb/S ratio |
|---|---|---|
| PbS:OA | n.a. | 1.58 ± 0.08 |
| PbS:TBAI | 0.336 ± 0.010 | 1.51 ± 0.14 |
| PbS:TBAI/BQ | 0.353 ± 0.016 | 1.45 ± 0.04 |
| Simulated PbS QDs | 0.302 | 1.47 |
