Abstract

In this paper, We have studied Electron Transport Layer(ETL) in the New Organics applied to Red phosphorescent organic light-emitting devices. The structure of ITO/2-TNATA(15nm)/CBP;$Ir(piq)_3$/DPVBi(30nm)/New ETL(60nm)/LiF(0.5nm)/Al(100nm) has been used, measured changing doping concentration of EML. The results of OLED turn-on voltage at 2.2V, and Maximum Luminance at 2.8V was $1000cd/m^2$. This high luminance at low voltage results from a high electron. conduction of the new electron transport layer.
