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.

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
