Abstract

In this report, current-voltage (I/V) curves, output luminance of the OLEDs (organic light emitting diodes) with nitrogen (N₂) doped ETL (electron transport layer) have been studied in detail. Experimental results show that the turn on voltage and driving voltage of OLEDs with ETL evaporated in the optimum N₂ gas ambient pressure of 1times10^-4 torr are reduced from 3.5 V to 1 V and 7.7 V to 5.7 V, respectively. The significant improving mechanism has been illustrated comprehensively with a schematic energy diagram model.
