Abstract :
In magnetic OLEDs, nanodot ferromagnetic cobalt(Co) electrode that provides highly efficient spin injection into organic semiconducting polymers in the study of magnetic field-dependent electroluminescence is found. Using spin injection and magnetoresistance to magnetically control the dynamic processes of singlet and triplet excited states in organic semiconductor devices is reported.
