<jats:p>A blue phosphorescent p–i–n homojunction organic light-emitting device with a low driving voltage was demonstrated using 4,6-bis[3-(carbazol-9-yl)phenyl] pyrimidine (46DCzPPm) as the bipolar host material and iridium(III) bis[4,6-(difluorophenyl)pyridinato-<jats:italic>N</jats:italic>,<jats:italic>C</jats:italic><jats:sup>2</jats:sup>'] picolinate as the blue triplet emitter. The device incorporated an n-doping electron-transport layer consisting of Cs<jats:sub>2</jats:sub>CO<jats:sub>3</jats:sub>-doped 46DCzPPm and a p-doping hole-transport layer consisting of MoO<jats:sub>3</jats:sub>-doped 46DCzPPm. A maximum external quantum efficiency of 10.2% and a power efficiency of 27.8 lm W<jats:sup>-1</jats:sup>were obtained. At 100 cd m<jats:sup>-2</jats:sup>, the efficiencies were 9.1% and 21.5 lm W<jats:sup>-1</jats:sup>, and even at 1000 cd m<jats:sup>-2</jats:sup>, the efficiencies remained at 7.0% and 12.8 lm W<jats:sup>-1</jats:sup>, respectively, with an extremely low driving voltage of 3.9 V.</jats:p>
