Fabrication of organic light emitting diode with a microlens structure by functional polymer colloid

我们计划利用聚合物电沉积方法建立有机电致发光二极管(OLED)的新制造工艺。为了构建OLED发光层，我们制备了空穴传输化合物和电子传输发光材料两种胶体。首先，我们通过抗蚀剂材料在ITO电极上有规律地制造了大量的圆形开口。我们连续地将这些制成的胶体朝向ITO电极上的无数圆形开口进行了电泳化。然后将这些胶体堆积在一起，制成发光层。此外，我们还在发光层上制备了阴极。我们在发光层上施加电场，然后观察发光层的电致发光。

We planed to establish the novel fabrication process of organic light emitting diode(OLED) with the use of the polymer electrodeposition method. To make up the light emitting layer of OLED, we prepared two kinds of colloids consist of the hole transporting compounds and the electron transporting luminescent materials. At first, we created numerous circular openings regularly on the ITO electrode by the resist materials. Consecutively, we electrophoresed those fabricated colloids toward the numerous circular openings on the ITO electrode. Those colloids were piled up, then, the light emitting layer was fabricated. Moreover, we prepared the cathode electrode on the light emitting layer. We impressed the electric field upon the light emitting layer, and then we observed the electroluminescence from the light emitting layer.
