After the first report of a bright green light organic electroluminescent(EL) device by Tang and Van Slyke,intensive research efforts have been made to realize other emission colors. Various emission colors,including blue,green,red and white,can be obtained at high luminance levels,which promises the application of these devices to flat panel full color displays.Among them,white light emission is very important for applying organic EL devices to full display,backlight and illumination light source.Owing to the lack of the single active material,which emits white light,several fluorescent dyes with different emission colors should be used to generate white light.Therefore,it is necessary to develop special device structures for this purpose. This work have developed a high brightness and efficiency white light devices.The device structure of ITO/poly(N vinylcarbazole)(PVK)/1,1,4,4 tetraphenyl 1,1,3 butadiene(TPB)/aluminum complex(Alq)doped with rubrene/Alq/Mg/Al was employed.The turn on voltage is as low as 2 5V.Blue fluorescent TPB,orange fluorescent rubrene,and green fluorescent Alq are used as three primary colors.The Commission Internationale de 1′E clairage(C.I.E)coordinates of the emitted light are (x=0 319,y=0 332)at 10V,which is located in the white light region.Bright white light,over 20000cd/m 2,was successfully obtained,and the maximum efficiency reaches to 1 24lm/W at 9V. In this paper,the structure of the white light emitting device belongs to common multilayer structures,but at present the brightness and efficiency of the device was in the lead in international reported white light emitting devices.The reason the author considered probably are as follows:polymer PVK acts as hole transport layer,the thick PVK layer(200nm)can not only reduce the amount of pinhole of the film, enhance the evenness of the film,but also reduce hole current,namely majority current,which benefit to charge carrier injection balance and improve the formation probability of exciton,and at the same time,the thick PVK layer can depress the jouleheat made by largger current,bring down the effect of heat on fluorescence efficiency of organic material,which also benefit to achieving high performance devices.
