We demonstrated efficient simplified orange and white organic light-emitting devices based on a platinum(II) complex Tetra-Pt-N. The maximum current efficiency achieved from the optimized orange device was 57.6 cd/A. The emission mechanism for the system of Tetra-Pt-N doped into 4,4'-bis(arbazole-9-yl)biphenyl was discussed. Moreover, a high-efficiency and simplified white device was fabricated by introducing an ultra-thin blue phosphorescent emission layer. The white device with a maximum current efficiency of 41.9 cd/A showed excellent stable spectra and low efficiency roll-off.
我们展示了基于铂（II）配合物Tetra-Pt-N的高效简化橙色和白色有机发光器件。优化后的橙色器件实现的最大电流效率为57.6 cd/A。讨论了掺杂到4,4'-双（咔唑-9-基）联苯中的Tetra-Pt-N体系的发光机制。此外，通过引入超薄蓝色磷光发射层制备了一种高效简化的白色器件。最大电流效率为41.9 cd/A的白色器件表现出优异的稳定光谱和低效率滚降。
