  • To improve the performance of top-emitting organic light-emitting diodes (TEOLEDs), the effect of oxygen plasma treatment duration on the electrical properties of multi metal Ni/Ag/Ni thin film anodes was investigated. The results revealed that a Ni/Ag/Ni thin-film layer formed upon oxygen plasma treatment for 180 s effectively increased electron-hole recombination probability by improving their charge balance.
