چکیده انگلیسی
Improved performance of organic light-emitting diodes (OLEDs) as obtained by a mixed layer was investigated. The OLEDs with a mixed layer which were composed of N,Nâ²-diphenyl-N,Nâ²-bis(1-napthyl-phenyl)-1,1â²-biphenyl-4,4â²-diamine (NPB), tris-(8-hydroxyquinolato) aluminum (Alq3) and 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) showed the highest brightness and efficiency, which reached 19048Â cd/m2 at 17Â V and 4.3Â cd/A at 10Â mA/cm2, respectively. The turn-on voltage of the device is 2.6Â V. Its Commission Internationale del'Eclairage (CIE) coordinate is (0.497, 0.456) at 17Â V, and the CIE coordinates of the device are largely insensitive to the driving voltages, which depicts stabilized yellow color.
