Fig. 3: EL spectra and g-factors.
From: Simultaneous emission of orthogonal handedness in circular polarization from a single luminophore
a–c EL spectra for various twisted angles Tθ (a Tθ = 0° and b Tθ = 52° without chiral dopant, and c Tθ = 100° with 2.5 wt% of chiral dopant). The EL spectra measured without a circular polarizer, and with LH and RH circular polarizers are presented by black (IT), red (IL), and blue (IR) solid lines, respectively. d |gEL| as a function of the twisted angle. The filled circles represent experimentally measured values from the CPEL (red and green symbols represent the gEL values of the pure F8BT without the chiral dopant and those of the F8BT with the 2.5 wt% chiral dopant). Using the Mueller matrix analysis, |gEL| calculated as a function of the twisted angle at different recombination zone of 0 (black solid line), 40 (blue solid line), and 80 nm (red solid line) from the TPBi. e Schematic diagram of the CPEL mechanism.
