From the viewpoint of practical application, enhancing the stability and lifetime of organic lightemitting diodes (OLED) is a al of research. A MgF₂ modified tris(8-hydroxyquinoline)-aluminum (Alq₃) hybrid superstructure was realized by collosol infiltration of a Mg(CF₃COO)_2-x(CH₃COO)_x precursor onto Alq₃. Alq₃ was well-dispersed in a large amount of Mg(CF₃COO)_2-x(CH₃COO)_x gel precursor solution, and after concentration a well-dispersed composite paste was produced. By heating the paste to 300 ℃, Alq₃ transformed to the superstructured ε-phase, and MgF₂ homogeneously incorporated because of od gel precursor infiltration and in situ deposition. The MgF₂-modified Alq₃ nanocomposite with superstructure has the same electroluminescence (EL) spectrum as Alq₃, with a dramatic improvement of the anti-aging performance of the OLED compared with Alq₃ because of the uniform assembly and well-defined structure. The effect of the amount of Mg(CH₃COO)₂ reactant on the OLED device anti-aging performance was investigated. The results showed that for the Alq₃-MgF₂ nanocomposite with 5% (molar fraction) of the Mg(CH₃COO)₂ reactant, the luminance remained at the initial state of 93.5% after aging for 72 h in air. However, the luminance of the Alq₃-based OLED almost disappeared after aging for 24 h under the same conditions. This work on inorganic material modified luminescent materials makes significant progress towards stable OLED.
