Abstract
In recent years, the emission of triplet state of organic-transition metal complex at tracted extensive attentions with the development of OLED devices. It not only concerns with the increase the device efficiency, but also with some problems deeply in the field of photo physics. In this article, the energy level splitting of organic-metallic compounds, and the zero field splitting (ZFS) of emissive triplet state are discussed briefly. Simultaneously, the rela tionship of electronic configuration of centered metallic ions, such as the octahedral and square planar coordination and their photo-physical behaviors are also discussed. Especially, the emis sion state of these compounds, under the influence of spin-orbital coupling(SOC) and configu ration interaction (CI) which can induce the admixture of singlet and triplet state, then to im prove the emissive transition from the lowest triplet state to ground state, has also been dis cussed.关键词
