초록

To understand the electronic charge transfer from cathode to an ETL in the TEOLED, the pristine $Alq_3$ thin film and the interfaces of both $Alq_3/Ba$ and $Alq_3/Au$ were investigated by using the NEXAFS spectroscopy. The unoccupied energy state of each interface using the NEXAFS Analyses at the C and OK-edges was assigned and charge transfer from Ba to ${\pi}^{\ast}$ of $Alq_3$ was investigated in detail.
