OLED Structure Optimization for Pure and Efficient NIR Electroluminescence of Nd³⁺ Complexes Bearing Fluorinated 1,3-Diketones.

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 Nd³⁺ 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^-2%. Blueish-green emission from exciplex and electroplax formations was almost suppressed with the topology optimization of the cell.
