摘要Abstract: This paper demonstrates that a flexible organic light-emitting diode (OLED) with a platinum
(Pt)-doped indium tin oxide (ITO) anode could show superior electro-optical characteristics to
those of a conventional device. The threshold voltage and turn-on voltage of an OLED device
consisting of an aluminium/lithium fluoride/tris(8-hydroxyquinoline)
aluminium/N,N-bis-(1-naphthyl)-N,N-diphenyl-1,1-biphenyl-4,4-diamine/Pt-doped
ITO/ITO structure were reduced by 1.2V and 0.8V, respectively. Current efficiency was found
improved for a driving voltage of less than 6.5V as a result of the enhanced hole-injection rate,
attributed mainly to the elevated surface work function and partly reduced surface roughness
of ITO by the incorporated Pt atoms in the ITO matrix.
