Multilayer　transparent　electrode　based　on　Al-doped　zinc　oxide　(AZO)/Ag/Al-doped　zinc　oxide　(AZO)　was　fabricated　by　sputtering,　and　a　green　organic　light-emitting　diode　(OLED)　device　utilizing　AZO/Ag/AZO　as　anode　was　fabricated.　The　AZO/Ag/AZO　multilayer　film　exhibited　superior　square　resistance　and　optical　transmittance　to　those　of　commercial　indium　tin　oxide　(ITO).　In　comparison　with　the　green　OLEDs　based　on　ITO　and　pure　AZO　anode,　the　green　OLED　based　on　AZO/Ag/AZO　showed　the　highest　light-emitting　efficiency.　The　results　indicate　that　AZO/Ag/AZO　multilayer　electrodes　are　a　promising　low-cost,　low-toxic　and　low-temperature　processing　electrode　scheme　for　OLED　application.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
