The investigation whether a material is suitable for the use of organic light-emitting diodes can be outsourced to the IFW Dresden. With our long-standing expertise and comprehensive analysis of a variety of spectroscopic methods, which are combined with electrochemistry, changes in structure, properties and stability can be followed in situ. Only materials of purely organic compounds, organometallic complexes or electroactive polymers can be analyzed by the described methods.
| Determination of charge carriers (radical ions, diions etc.) generated electrochemically in layer material (e.g. HTM, ETM, HIL) |
| Study of optical and magnetic properties and stability of charge carriers |
| Evidence for the formation of byproducts affected device degradation |
| State-of-the-art equipment and expertise for studies of the electrochemical electron transfer using Nuclear magnetic resonance (NMR), Electron spin resonance (ESR/EPR), Raman, Fourier Transform Infrared (FTIR), Ultraviolet-visible-near-infrared absorption (UV-vis-NIR) and Luminescence spectroscopy |
| Accurate in situ spectroelectrochemical technique, e.g. triple method ESR/ UV-vis-NIR/ cyclic voltammetry |
| FTIR/ cyclic voltammetry spectroelectrochemistry |
