摘要:

提高有机电致发光器件(OLED)的稳定性和寿命是其市场化应用中需要解决的关键问题. 本文从提高发光材料自身的稳定性出发, 以Mg(CF₃COO)_2-x(CH₃COO)_x溶胶为前驱体, 将其与8-羟基喹啉铝(Alq₃)混合浓缩成糊状后, 300 ℃真空烧结, 经过MgF₂的生成和Alq₃的相变后, 形成了一系列Mg含量不同的具有超结构ε相的纳米复合材料Alq₃-MgF₂. 研究结果表明, 相比于纯Alq₃, Alq₃-MgF₂纳米复合材料制备的OLED可以很好地保持Alq₃的发光特性, 同时, 其抗老化性能得到显著提高. 特别是, Mg(CH₃COO)₂投料量为Alq₃的5% (摩尔分数)时,所得Alq₃-MgF₂纳米复合材料制备的器件抗老化性能最优, 在空气中老化72 h, 最大发光亮度仍保持在起始值的93.5%; 而Alq₃制备的OLED在空气中老化24 h后基本失活.

Abstract:

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.
