Abstract
White polymer light-emitting diode with a single layer of fluorescent polymer blend was fabricated. The structure of the device is indium tin oxide/poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate)/emission layer/1,3,5-tris(N-phenylbenzimidazol-2-yl)-benzene/Ba/Al, and the emission layer is a blend of poly［2,7-(9,9-dioctyl)fluorene-co-2,3-bis(4-phenyl)-6-fluoroquinoxaline］ (PF-BPFQ5), phenyl-substituted poly(p-phenylene vinylene) derivative (P-PPV) and poly［2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene］ (MEH-PPV), which, respectively, emits blue, green and red light. When the blend weight ratio of PF-BPFQ5∶P-PPV∶MEH-PPV is 100∶06∶06, a pure white light emission is obtained with CIE coordinates of (0331,0329). The maximal luminance efficiencies is 564 cd/A. Meanwhile, the electroluminescence spectrum of white-light emission is stable under different current densities.
