| Abstract: | High efficient undoped blue organic light|emitting devices (OLEDs) with a typical structure of ITO/2T|NATA(40 nm)/NPB(10 nm)/N-BDAVBi((3+d) nm)/ADN(7 nm)/N|BDAVBi((3+d) nm)/ADN(7 nm)/Alq3(30 nm)/LiF(0.5 nm)/Al were prepared by means of thermal vacuum deposition method with N|BDAVBi as the emitting layer. The results show that the device has a maximum luminous efficiency of 4.38 cd/A at 6 V when the thickness of N|BDAVBi layer is 7 nm, and the device has a maximum luminance of 13 200 cd/m2 at 13 V when the thickness of N|BDAVBi layer is 11 nm. The CIE coordinates of the device are within the blueregion when the voltage changes from 0 V to 13 V. |
