26. Solution concentration estimated at ∼5 mg/mL concentration, with an optical density over 1 at the first exciton, if measured in a 1 cm cuvette.
27. The airtight optical cell consists of two windowed UHV con-flat pieces that are sealed together with a copper gasket, making an airtight metal-to-metal seal.
28. We note that the PbTe QD film showed similar behavior, but this data is not shown for brevity.
29. -1 allows us to ensure proper alignment of the air-free cell, after which alignment, the cell containing the PbX film is dropped into place.
