Abstract
We demonstrate an improved efficiency in OLEDs with a thin Alq3 interlayer, which is inserted into the hole-transport layer for adjusting the hole-injection and transport, and improving the hole-electron balance. The thin Alq3 interlayer can effectively influence the electrical performance and electroluminescence (EL) efficiency of the devices. The devices with an optimum Alq3 interlayer exhibit a maximum EL efficiency of around 3.3 cd/A, which is improved by a factor of two over the conventional devices (1.6 cd/A) without the interlayer.
