Abstract

A fluorescent non-doped white organic light-emitting device (WOLED) with double emissive layers was fabricated. The yellow and blue dyes, 4- (dicyanomethylene) -2-t-butyle-6-(1, 1, 7, 7- tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) and 9, 10-di (2-naphthyl) anthracene (ADN), can be realized by blending complementary colors. The maximum current efficiency and power efficiency of the WOLED are 7.61cd/A at 9V and 2.1l m/W at 8V, with the maximum brightness of 15840 cd/m2 at 12V. The Commission International deL'Eïclairage coordinates change slightly from (0.5154, 0.4754) to (0.4602, 0.4427), as the applied voltage increases from 4V to 12V. The high efficiencies can be attributed to the decrease concentration quenching of fluorescence dye.
