利用一种新型有机金属配合物二(2-(4-三氟甲基-2-羟基苯基)苯并噻唑锌(Zn(4-TfmBTZ)2),基于NPB/Zn(4-TfmBTZ)2界面电致激基复合物,制备了一系列异质结量子阱结构有机电致白光器件.结果表明,量子阱结构可以有效提高界面电致激基复合物的发光效率以及器件的显色指数和色度稳定性.得出器件ITO/NPB(60nm)/Zn(4-TfmBTZ)2(3.0nm)/NPB(4.0nm)/Zn(4-TfmBTZ)2(30nm)/Alq3(30nm)/LiF(1.5nm)/Al(150nm)的性能最佳,在10—14V的电压驱动下,色坐标基本稳定在(0.324,0.337)附近,最高显色指数为92.5,最大亮度为2013cd/m2,最高发光效率为1.03cd/A.
(4-TfmBTZ) 2 based on NPB / Zn (4-TfmBTZ) 2, a new organometallic complex, A series of heterojunction quantum well structure organic electroluminescent devices were prepared.The results show that the quantum well structure can effectively improve the luminous efficiency of the interface electrochromic complex and the device’s color rendering index and Chrominance stability was obtained for the devices ITO / NPB (60nm) / Zn (4-TfmBTZ) 2 (3.0nm) / NPB (4.0nm) / Zn (4-TfmBTZ) 2 (30nm) / Alq3 (30nm) (1.5nm) / Al (150nm) is the best.
