Light emission from exciplex of organic electroluminescent device

摘要

We report on the light emission from exciplex in a bilayer OLED with Z 12 as hole transporting material and BBOT as electron transporting material. PL, EL and the fluorescence lifetime measurements imply that the exciplex was formed by the interaction between the excitons and the ground state molecules at the interface of Z 12 and BBOT layers.
