Abstract :
We demonstrated the organic light-emitting diodes (OLED) with additive such as 2-propanol (IPA) in poly(3,4-ethylenedioxythiophene): polystyrene sulphonate (PEDOT:PSS). IPA mixed PEDOT: PSS showed a significantly decreased contact angle on ITO compared to those without IPA. On the other hand, the luminous efficiency of the devices using PEDOT: PSS mixed with 10% and 20% IPA were decreased due to the diluted solution of PEDOT: PSS. However, it solved by increasing the conductivity of PEDOT: PSS film with addition of dimethyl sulfoxide (DMSO).
