Figure 1. (a) Degree of Bi incorporation into PbS QDs using the two doping mechanisms provided by ICP-OES experiments.

Data for doping during synthesis have been taken from²¹, (b) Normalized absorbance of series A (doping during synthesis) films at 300K, (c) Normalized absorbance of series B (post-synthetic doping) films at 300 K, (d) Comparative integrated PL of the films of the two series at 300 K. The integrated PL has been normalized to the respective of the undoped films, (e) Comparative PL spectra of series A films at 300 K, (f) Comparative PL spectra of series B films at 300 K.
