초록
We describe flexible organic light-emitting diodes (OLEDs) with indium tin oxide (ITO) anodes fabricated at low substrate temperatures using facing target sputter (FTS) on a transparent-cellulose substrates. The device structure was cellulose paper substrate/SiO2/ITO/NPB/Alq(3):C545T/BCP/LiF/Al. The ITO thin films were deposited at substrate temperatures below 70 degrees C. X-ray diffraction analysis revealed that the ITO thin films were amorphous. As the substrate temperature during deposition increased from 27 to 70 degrees C, the sheet resistivity decreased from 1,400 to 120 omega/. The OLEDs with ITO thin film anode with sheet resistivity of 120 omega/ exhibited a maximum luminance of 14,543 cd/m(2) at a driving voltage of 14.75V.
