Exciplex/Electroplex Coexistence Magnetoconductance

Tunable magneto-efficiency sign

In a coexistence system of exciplex and electroplex, the sign of magneto-efficiency (Mη) can be tuned from negative to positive by adjusting ambient temperature or donor/acceptor blending ratio, offering a new method to probe spin-pair microscopic mechanisms in dual-emission systems.

Advantages

Low-field Mη transitions from negative to positive with decreasing temperature or increasing donor ratio

Normalized EL spectra show exciplex peak increases with decreasing T

Electroplex peak is impaired with increasing donor content
