Abstract

Recombination zone distribution can be determined by fitting the current-voltage characteristics and spectra of the ambipolar organic light-emitting device (OLED). Besides, a thin probe was inserted at different positions of the device to directly monitor the recombination distributions. Furthermore, it increases the recombination current and improves the power efficiency.
