Heraeus is introducing new polymer OLED materials. The HIL-E grades is a combination of Hole Injection Layer and a high conductive electrode - and so provide an economic ITO alternative. These are PEDOT formulations designed for the OLED lighting industry.
The HIL-E materials feature excellent planarization properties and a refractive index that matches glass and plastic substrates. The formulations are also pH neutral. Regular and high work function grades are available. These polymer-based materials are suitable for slot-die coating, ink-jet printing and other deposition processes.
