Polarized Emission from Conjugated Polymer Chains Aligned by Epitaxial Growth during Off-Center Spin-Coating

Figure 5

F8BT and MEH-PPV XRD pattern observed either at the center of spin-coated samples without TCB or in off-center spin-coated samples with TCB. The dark blue and orange arrows correspond to the molecular packing peaks for F8BT (at 5.1°, 1.7 nm) and MEH-PPV (at 4.8°, 1.85 nm), respectively.
