摘　　要： 利用高真空有机分子束沉积系统,我们选择了一种较好的蓝光材料4,4'-bis(2,2,'-diphenylbinyl)-1,1'-bipheny1(DPVBi)和黄光材料5,6,11,12,-tetraphenylnaphthacene(rubrene)采用适当的比例相混合产生白光效果,制备了近白光有机电致发光器件.在电压为16V时器件的亮度达到了最大值接近4272cd/m2,器件的效率在电压为5V时为3.3cd/A,在电压为15V时器件的色坐标(0.34,0.36),比较接近白光的等能点. Organic approach white organic light-emitting devices are successfully fabricated by using vacuum deposition system at a base pressure of 1×10^(-5) Pa.These were choosed by a good many blue fluorescent 4,4'-bis(2,2,'-diphenylbinyl)-1,1'-bipheny1 (DPVBi) and orange fluorescent 5,6,11,12,-tetraphenylnaphthace ne (rubrene) .then complex these ,a white light-emitting have emerged. We discussed the emission mechanism of the devices, which is due to the blue and yellow emission of DPVBi and rubrene, respectively. A approach white organic light-emitting devices are fabricated. The maximum luminance and efficiency of the device are 4 272 cd/m^2 at 16V and 3.3 cd/A at 5 V, respectively, which produces fairly pure white emission with the commission international De L'Eclairage coordinates of (0.34,0.36) at 15 V.
