    • Light extraction from wet-coated OLED devices may be improved by optimizing the charge injection or transport layers to direct more light into a supporting substrate, thus maximizing the final light extraction efficiency. Accordingly, in one aspect, the present invention relates to an optoelectronic device (20) that has at least one charge carrier injecting or transporting layer (3) that includes inorganic nanoparticles (11, 12) having a bimodal particle size distribution and dispersed in an organic matrix. In another aspect, the present invention relates to an optoelectronic device (10) that includes an electron transporting layer (6) comprising inorganic nanoparticles (11) dispersed in an organic matrix. In yet another aspect, the present invention relates to an optoelectronic device (30, 40) wherein the surface of the electron transporting layer (6) that is contiguous to the cathode is uneven (14). In yet another aspect, the present invention relates to an optoelectronic device comprising • a substrate; • an anode; • a cathode; • an electroluminescent layer; and • electron transporting layer comprising a fluoro compound of formula I (Ar2)n -Ar1-(Ar2)n I wherein Ar 1 is C 5-C 40 aryl, C 5-C 40 substituted aryl, C 5-C 40 heteroaryl, or C 5-C 40 substituted heteroaryl; • Ar 2 is, independently at each occurrence, fluoro- or fluoroalkyl- substituted C 5-40 heteroaryl; and • n is 1, 2, or 3.
    • 可以通过优化电荷注入或输送层以将更多的光引入支撑衬底来改善从湿涂层OLED器件的光提取,从而使最终的光提取效率最大化。 因此,一方面,本发明涉及一种具有至少一个载流子注入或传输层(3)的光电器件(20),该载流子注入或输送层(3)包括具有双峰粒度分布的无机纳米颗粒(11,12) 有机基质。 另一方面,本发明涉及包括分散在有机基质中的包含无机纳米颗粒(11)的电子传输层(6)的光电子器件(10)。 在另一方面,本发明涉及一种光电器件(30,40),其中与阴极邻接的电子传输层(6)的表面是不均匀的(14)。 在另一方面,本发明涉及一种光电子器件,其包括:衬底; •阳极; •阴极; •电致发光层; 和包含式I(Ar2)n -Ar1-(Ar2)n I的氟化合物的电子传输层,其中Ar 1是C 5 -C 40芳基,C 5 -C 40取代的芳基,C 5 -C 40杂芳基, 或C 5 -C 40取代的杂芳基; •Ar 2在每次出现时独立地为氟或氟烷基取代的C 5-40杂芳基; 和•n为1,2或3。
