Abstract: (833 Views)
Pretreatment of the indium tin oxide (ITO) surface is generally adopted to improve the charge injection and device performance in the fabrication of organic light-emitting diodes. In this study, the ITO films were terminated by 80 w on oxygen plasma for 4, 6 and 8 min. The treatment of ITO films improved the structure, reduced the average size of nanocrystals and reduced their surface roughness. The ITO films were used in the fabrication of the diode with Glass/ITO/PEDOT:PSS/Alq3/Al structure. The treatment of ITO films has reduced the threshold voltage and increased the light intensity of the diodes.
