Chemical Structure
Characterization
Applications
For a high-efficiency green OLED we recommend blending F8 with F8BT with the below specifications. This ink can then be applied either in air, or in a glove box, with little difference in performance (provided exposure time and light levels are minimised). For more details see our fabrication guide.
At typical concentrations of 10 mg/ml, 100 mg of F8 (PFO) will make around 200 devices on Ossila's standard ITO substrates (20 x 15 mm), assuming 50% solution usage (50% loss in filtering and preparation).
OLED reference device:- F8 with F8BT
- Blend ratio of 19:1 (F8:F8BT) in Toluene
- Total concentration of 10 mg/ml
- 0.45 μm PTFE filter (hydrophobic)
- Spun at 2000 rpm (approx. 70 nm thickness)
Pipetting 20 μl of the above solutions onto a substrate spinning at 2000 rpm should provide a good even coverage, with approximately 70 nm thickness. The substrate needs to be spun until dry, which is typically only a few seconds — 15 seconds should be ample to achieve this. Thermal annealing should be undertaken at 80°C for 10 minutes prior to cathode deposition.
Typical Device Architectures and Performance
A basic, efficient OLED can be made using PEDOT:PSS as a hole-transport layer and Calcium/Aluminum as the electron contact. When used with the Ossila ITO glass OLED substrates and shadow masks this produces an easy to fabricate yet efficient >100 cd/m2 device.
