An organic LED (OLED) consists of a high-brightness, light-emitting material with a low turn-on voltage for improved battery life. Understanding these materials requires a thorough analysis of its electronic structure. Thermo Scientific X-ray photoelectron spectrometers combine several surface analysis techniques in one instrument, enabling in-depth OLED research.
Download the application note to learn how:
- XPS provides information about surface contamination and film purity
- REELS investigates the electronic structure
- UPS provides information about the valence energy levels
- Taken together REELS and UPS create an energy level diagram of an organic thin-film material
