||In recent year, there are many research on improving conductivity of PEDOT:PSS thin film by various of treatment for instead of ITO anode on the OLED device. The ITO thin film is inflexible, if we fabrication flexible OLED ITO is not unsuitable for FOLED. For example, Doping, Dropping, Soaking, treatment by different solvent has been proofed that can enhance conductivity of PEDOT:PSS to 3-4 orders enhanced than before treatment. |
In this research, we will use Dope, Soak and Drop treatment by DMSO, Glycerol, formic acid, Methanol and Hydrochloric acid. We compare the change of PEDOT:PSS thin film before and after the treatment by using four-point probe, Alpha step, UV-vis, Raman spectrum, XPS spectrum, AFM and PESA.
We successfully enhance the conductivity of PEDOT:PSS from 0.3(S/cm) to 1244 S/cm by stabilizing, easy, liable and height adaptation method. Finally, we manufacture PEDOT:PSS anode device by doping treatment. At the luminance 1000 cd/m2, the performance of current efficiency are 18.5 (cd/A), power efficiency are 6.3 (lm/W), 6.9 (lm /W), EQE are 9.1(%).
