We have prepared an organic EL device with an ITO/PVCz (polyvinylcarbazole)/Alq/SrO<jats:sub><jats:italic>x</jats:italic></jats:sub>/Al structure. SrO<jats:sub><jats:italic>x</jats:italic></jats:sub> was stacked as an electron injection layer on the Alq (aluminum quinolinol complex) emission layer by means of a reactive vapor deposition method by evaporating metallic strontium under an oxygen atmosphere. By inserting the SrO<jats:sub><jats:italic>x</jats:italic></jats:sub> film of less than 5 nm in thickness, significant improvements were achieved in the device properties, including luminance, lifetime, threshold voltage, and efficiency. XPS measurement and AFM analysis showed that the film morphology of the SrO<jats:sub><jats:italic>x</jats:italic></jats:sub> layer had an island structure. The oxidation of SrO<jats:sub><jats:italic>x</jats:italic></jats:sub> was enhanced by setting the oxygen partial pressure for the reactive vapor deposition to 10<jats:sup>−3</jats:sup> to 10<jats:sup>−2</jats:sup> Pa, which yielded the optimum EL properties. © 2003 Wiley Periodicals, Inc.
