Lead Sulfide Quantum Dots

AbstractA modified Z-scan method for determining the nonlinear refractive index of colloidal quantum dots in the near-IR spectral range in the resonant excitation mode is proposed. It is demonstrated that the thermal effects related to heating of the solution due to strong light absorption can be mitigated by reducing the probing pulse repetition rate. The nonlinear refractive index of colloidal lead sulfide quantum dots is found to be on the order of 10^–16 cm^2/W.

Photovoltaic Materials

Among solution-processed photovoltaic materials, lead sulfide (PbS) colloidal quantum dots (QDs) possess a highly tunable bandgap and strong infrared absorption, while perovskites show extraordinary external quantum efficiency (EQE) in the visible region, which offers the opportunity to construct an ideal tandem cell of PbS QDs/perovskite.
