Abstract
We have investigated the relationship between electroluminescent (EL) device performance and electron injection properties on the basis of the Schottky emission model. The EL device with dithienosilole derivatives (DTS) as an electron injection layer has a lower energy barrier (0.33 eV) for electron injection from magnesium compared to that (0.43 eV) of a typical EL device without DTS. This may lead to the improvement in the electrical properties of the EL device with DTS.Keywords
