Abstract

NIR emitting OLEDs (organic light-emitting diodes) with high photoluminescence quantum yields were developed on the basis of fluorinated 1,3-diketonate coordination compounds of the Nd ion. Both thermal evaporation and spin-coating techniques were successfully employed for active layer deposition resulting in electroluminescence quantum yields up to 1.38·10%. Blueish-green emission from exciplex and electroplax formations was almost suppressed with the topology optimization of the cell.

摘要

基于钕离子的氟化1,3 - 二酮配位化合物开发出了具有高光致发光量子产率的近红外发光有机发光二极管（OLED）。热蒸发和旋涂技术均成功用于活性层沉积，从而实现了高达1.38·10%的电致发光量子产率。通过电池的拓扑优化，几乎抑制了激基复合物和电激子形成产生的蓝绿色发射。
