The dc magnetic-field effect vs the drive-dependent singlet (lower axis) and triplet (upper axis) concentrations. Direction of magnetic field, , is indicated in the figure. The dashed line estimates the fractional singlet contribution from TTA, which is negligible when is largest, excluding TTA as the origin of .

(a) EL (dashed) and (solid) during and after the drive pulse for the device, showing enhanced when singlet emission is low. (b) Expanded time scale after the pulse (note new zero of time). Dashed arrows indicate trends in EL as a reverse bias applied at the end of the drive pulse was varied (0, , , ). Response of delayed EL to bias shows charge carriers are the main source of EL. The curve referred to on the right-hand side axis is a typical transient ( reverse bias is shown).
