A Novel Buffer Layer of Alq3 in Organic Electroluminescent Devices
-
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.
