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