Abstract

We have fabricated stable efficient iridium(iii)-bis-5-(1-(naphthalene-1-yl)-1-phenanthro[9,10-]imidazole-2-yl) benzene-1,2,3-triol (acetylacetonate) [Ir(NPIBT) (acac)] doped inverted bottom-emissive green organic light-emitting diodes using Ti-doped ZrO nanomaterials as the electron injection layer. The current density () and luminance () of the fabricated devices with Ti-doped ZrO deposited between an indium tin oxide cathode and an Ir(NPIBT) (acac) emissive layer increased significantly at a low driving voltage (V) compared with control devices without Ti-doped ZrO. The Ti-doped ZrO layer can facilitate the electron injection effectively and enhances the current efficiency ( ) of 2.84 cd A and power efficiency ( ) of 1.32 lm W.
