The authors report the fabrication of white organic light emitting devices and discuss their electroluminescence (EL) properties.The device structure is ITO / TPD (50 nm)/ BCP (8 nm)/ Rubrene (0.5 nm)/ BCP (10 nm)/ Alq3 (20 nm)/ LiF (lnm)/Al.In the EL spectra of this device,two new emissions peaking at 590 nm and 630 nm have been observed.These two emissions should be attributed to electroplex occurring at TPD/BCP interface after comprehensive analysis on the emission of each organic materials used in these experiments.White emission was obtained based on this device under 12V driving voltage,the Commission Internationale de 1 Eclairage (CIE) coordinates arrives to (0.31,0.33).
