    • Absolute PL quantum efficiency in both the solution and solid state was measured using a λ = 405 nm laser as the excitation source. The absorbed power was quantified using a Newport 818-UV-C/M silicon detector. The NIR signal was detected 15° off of the front face normal, 10 cm distant from the sample, with a silicon filter in place to block all reflected visible emission. The solid angle bisected by the 3 mm diameter germanium detector was taken into account when calculating the total NIR emission. The solution samples were measured in a 2 mm path length quartz cuvette, and the solid state samples were measured from drop-cast films that were isolated from oxygen to prevent photo-oxidation during the measurement. Relative PL quantum yield experiments reveal no dependence on excitation wavelength throughout the analyzed range of λ = 400 to 900 nm.
