Singlet Generation from Triplet Excitons in Fluorescent Organic Light-Emitting Diodes

Figure 5

Dependency of the rise of the transient triplet absorption signal (𝑇) on its corresponding fluorescence level (𝑆) for electrical and optical excitation on a double logarithmical scale. The two solid lines are least square fits of the offset of a strictly linear dependency. Data are given in volts from the original measurement from the oscilloscope.
