Abstract
A bilayer is used as an electrode for organic light-emitting devices. The bilayer consists of a Sn layer adjacent to Alq layer and an Al outerlayer. The effects of a controlled Sn buffer layer on the behavior of ITO/CuPc/NPB/Alq/Sn/Al light-emitting devices are described. It is found that both electron injection efficiency and electroluminescence are significantly enhanced when the thickness of Sn layer is suitable. The enhancement is believed to be due to increased electron density of Sn layer near the Sn/Al interface .
