Abstract

High efficiency blue organic light emitting diodes (OLEDs), based on 2-me-thyl-9,10-di(2-naphthyl) anthracene (MADN) doped with 4,4′-bis(9- ethyl-3-carbazovinylene)-1,1′-biphenyl (BCzVBi), were fabricated using two different electron transport layers (ETLs) of tris(8-hydroxyquinolino)-aluminum (Alq₃) and 4,7-di-phenyl-1,10-phenanthroline (Bphen). Bphen ETL layers favored the efficient hole-electron recombination in the emissive layer of the BCzVBi-doped blue OLEDs, leading to high luminous efficiency and quantum efficiency of 8.34 cd/A at 100 mA/cm² and 5.73% at 100 cd/m ², respectively. Maximum luminance of blue OLED with Bphen ETL and Alq₃ ETL were 10670 cd/m², and CIE_xy coordinates of blue OLEDs were (0.180, 0279) and (0.155, 0.212) at 100 cd/m ².
