초록

In this study, a micro-cavity organic light-emittingdevice (OLED) with semi-transparent-Ag/AgO hole injecting layer (HIL) was fabricated and their performance was investigated. For the fabrication of OLEDs N,N-diphenyl-N,N-(3-methyphenyl)-1,1-biphenyl-4-4-diamine (TPD), known as a hole transporting material and tris (8-hydroxyquinolinato)-aluminum ($Alq_3$) as both electron-transporting layer (ETL) and emission layer (EML) were deposited using thermal evaporation technique. And Al layer as cathode was then deposited using thermal evaporation technique. Effects of the semi-transparent-Ag/AgO layers on the resulting OLED performance were investigated.
