Uncovering the Role of Spacers in Advancing Portable, Low-Voltage OLEDs

Inserting a nanometer-thin spacer in ExUC-OLEDs improves energy transfer, enhances blue light emission 77-fold, paving way for lightweight, low-voltage, and more flexible OLEDs . The effect of spacer insertion depends on the dipole moment. Therefore, it is possible to extend the material selection tolerance for ExUC-OLEDs using appropriate spacer materials. ExUC-OLEDs can be driven at ...
