Fabrication of Transparent Electrodes Based on PEDOT∶PSS Conductive Polymer and Their Optoelectronic Propertie
The PEDOT∶PSS films with high conductivity and high transparency were prepared on glass and flexible plastic substrates via doping modification.The properties of the green standard OLEDs and yellow electrophosphorescence devices based on the PEDOT∶PSS anodes were further investigated.The flexible and flat OLEDs with(MPPZ)2Ir(acac)as dopant and CBP as the host were fabricated on ITO/glass,PEDOT∶PSS/glass and PEDOT∶PSS/PET substrates.The results show that the device based on PEDOT∶PSS/glass has a turn-on voltage of 3.83 V,and its maximum brightness and maximum current efficiency are 18 632 cd/m2 and 21.61 cd/A,demonstrating that the transparent and conductive PEDOT∶PSS films are very promising candidates as anode materials for OLEDs.
