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法建立有机发光二极管（OLED）的新型制造工艺。为了构成OLED的发光层，我们制备了两种由空穴输运化合物和电子输运发光材料组成的胶体。首先，我们通过抗蚀剂材料在ITO电极上有规律地创建了许多圆形开口。连续地，我们将这些制备的胶体电泳到ITO电极上的许多圆形开口上。将这些胶体堆积起来，然后制成发光层。此外，我们在发光层上制备了阴极电极。我们在发光层上施加电场，然后观察从发光层发出的电致发光。

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.
