چکیده انگلیسی
In this work, color/luminance tunable organic light emitting diodes (OLEDs) (ITO glass/naphthyl phenyl benzidine (NPB; 80Â nm)/4,4â²-bis(diphenylvinylenyl)-biphenyl (ADS082BE; 35Â nm)/1,3-bis[2-(2,2â²-bipyridine-6-yl)-1,3,4-oxadiazo-5-yl]benzene (Bpy-OXD; 20Â nm)/tris-[8-hydroxy-quinoline]aluminum (Alq3; 50Â nm)/lithium fluoride (LiF; 3Â nm)/aluminum (Al, 80Â nm)) with low turn-on voltage (3Â V) and high luminance (4850Â cd/m2 at 9Â V) have been successfully manufactured. The experimental results reveal that their electroluminescent properties (e.g. hue, luminescent intensity, etc.) can be modulated by the manipulation for the layer thickness of NPB/ADS082BE/Bpy-OXD and the applied voltages. In addition, we have also demonstrated lab-made UV-curable silicone-acrylate encapsulating resin exhibits excellent gas barrier capability so that the half-lifetimes of OLEDs reach 98Â h whereas those without encapsulation are only 9Â h.
