Abstract

A greatly enhanced proportion of radiative excitons in non-doped blue electroluminescence with a maximum exciton utilizing efficiency (EUE) of 85% is harvested in the orthogonal cyano substituted, charge transfer (CT) emitter TPMCN, in comparison to the localized emission (LE)-like emitter TPM with a low EUE of 16%.

摘要

在正交氰基取代的、电荷转移（CT）发射器 TPMCN 中，与具有低 EUE（16%）的局域发射（LE）类似发射器 TPM 相比，非掺杂蓝色电致发光中辐射激子的比例大大提高，最大激子利用效率（EUE）为 85%。
