Abstract Inserting the Alq₃ layer in the ITO/NPB interface as the buffer layer can improve the organic electroluminescent devices. The current density efficiency and power efficiency of the device with the Alq₃ buffer layer rises to 6.5 cd/A and 1.21 m/W at the current density of 120 mA/cm², respectively. The improvement is mostly attributed to the balance of the hole and the electron injections.
