Non-doped fluorescent white organic electroluminescent device based on perylene

Abstract

Abstract: By using two typical traditional fluorescent materials as the light-emitting layer, an non-doped all fluorescent white organic light-emitting diode (WOLED) is fabricated. In the device, two thin layers of perylene are located at both sides of ambipolar host material CBP (4,4’-N,N′-dicarbazole-biphyenyl) as blue emitters, an ultra-thin rubrene layer inserted into CBP as orange emitter. A simple and efficient OLED is obtained by varying the insertion position of rubrene in CBP, the highest current efficiency is 6.6 cd/A (external quantum efficiency is 2.6%), the maximum brightness is18 480 cd/m²,and Commission Internationale de l’Eclairage (CIE) co-ordinates can reach the ideal white light equilibrium point (0.33, 0.33) at a current density of 200 mA/cm².
