About us

The Fraunhofer IAP is active in organic electronic research focusing on applications in OLEDs, OTFT, OPV, sensors, and actuators. Synthesis of novel materials with improved optoelectronic properties, device design and manufacture are focal points. Quantum Dots (QDs) have tunable optical properties by means of adjusting particle size. Applications range from luminescent materials, displays or as converting material for lighting applications. The researchers achieve solution processability with printing techniques like inkjet and ESJET.

The Fraunhofer FEP works on innovative solutions in the fields of vacuum coating, surface treatment and organic semiconductors. The core competences are electron beam technology, sputtering, plasma-activated deposition, high-rate PECVD as well as technologies for organic electronics and IC/system design. Fraunhofer FEP offers a broad spectrum for R&D and pilot production, especially for OLED microdisplays, (in)organic sensors and flexible OLED lighting.

Products and services

The Fraunhofer FEP presents OLED microdisplays with new specifications that offer new applications (ultralow power display, large area microdisplay) and flexible OLEDs which can be produced on a variety of substrates and can be tailored to meet the customers’ special needs. Furthermore, examples of coatings (permeation barrier films, optical precision coatings,…) will be presented.

The Fraunhofer IAP has developed indium phosphide (InP) QDs covering a wide spectral range from green to red with a high quantum yield, low FWHM and high stability. Future display markets demand high-performance Cd-free QD-LEDs and multi-shell InP/ZnSe/ZnS QDs are the most promising candidates. The investigated QD-LEDs match the performance of Cd-based QD-LEDs with luminance values higher than 25.000 cd/m^2. Solution processability is achieved with printing techniques like inkjet and ESJET.

Quantum Dots

The Fraunhofer IAP has developed a method to provide very stable indium phosphide (InP) QDs covering a wide spectral range from green to red with a high quantum yield, low FWHM and high stability in organic and aqueous phases or other matrices. Developing the high-performance QD-LEDs based on InP-based QDs is quite important to bring QLEDs into the future market.

QD-LEDs

The Fraunhofer IAP investigated the performance of inverted QD-LEDs fabricated with synthesized multi-shell InP/ZnSe/ZnS QDs and ZnO nanoparticles for pixel areas down to 20 µm.

OLED Microdisplay Family

The Fraunhofer FEP offers a broad range of OLED microdisplays from ultra-low power, via bi-directional to large-area microdisplays. All of them have in common that they can be tailored to meet the customers’ special needs. So, they can be used in wearables and sensors as well as in VR- and AR-glasses.
