Table I: Photophysical and dielectric properties of DCM fluorophores at 0.1 wt% in PMMA:CAA films and calculated residual intensities using (Eq.4). Predicted values at εr =30 are included.
Supplementary Figure 1: Relative permittivity as a function of CAA weight percentage concentration, CCAA, is shown for films of the form PMMAx:CAA1-x:Dye0.1% at T = 20°C. Error bars are based on standard deviation over six devices per CCAA.
