    • A more complete treatment would calculate the angular dependence of the emission intensity of blue photons from the F8 molecules in region 1 and their subsequent re-absorption in the F8BT layer. We estimate that if all totally internally reflected blue light is re-absorbed this would increase the F8BT/F8 ratio by about 30, This would affect all samples systematically, and would be equivalent to an increase in Ax of approximately 2-4 nm compared to the calculation (Fig. 5) where only emission and reabsorption normal to the film is considered

    • A precise value for F8 is not available in the literature. The range of values for other conjugated polymers is from 5nm to 14nm. However, the study by Markov et al. [27] claims that the higher end of this range is an overestimation due to interdiffusion within the sample architecture.
