| Popis: | In this work we show the project and fabrication of a home-made blade coating system for deposition of solutions of organic semiconductor materials. The system was used for deposition of PEDOT:PSS, a common hole injection material in solution based organic light emitting diodes (OLEDs). Phosphorescent OLEDs were assembled with PEDOT:PSS deposited by blade coating and also by spin coating for comparison. Both devices presented similar performance with low leakage current and driving voltages around 6 V (at 20 mA/cm2). The efficiency for both devices was very similar (EQE $\sim$ 17%, at 20 mA/cm2) showing that the PEDOT:PSS film obtained by blade coating has similar hole injection properties and performance as the film deposited by spin coating. |
