摘要：

Angle-stable white top-emitting organic light-emitting devices (WTEOLEDs) by the combination of a blue TEOLED with a down-conversion (DC) layer are demonstrated. The DC layer is composed of red fluorescent dye doped in a host of tris (8-hydroxy-quinolinato) aluminum. The TEWOLED shows a CIE coordinates of (0.240, 0.332) and a maximum current efficiency of 3.95 cd/A. Furthermore, the WTEOLED shows excellently angle-stable characteristic, the CIE coordinates at 20 mA/cm(2) only shift by (0.023, -0.007) from 0 degrees to 60 degrees. It can be attributed to the angle-stable blue TEOLED based on the Ag/Ge/Ag transparent cathode. (C) 2014 Elsevier B.V. All rights reserved.
