在有机发光二极管（oled）中，电极与有机层之间的界面对其电学和发光性能起着重要的作用。氧化铟锡（ITO）是常用的阳极材料。利用射频磁控溅射技术将ITO薄膜沉积在玻璃衬底上，并将其用作OLED器件的阳极触点。采用热蒸发和自旋镀膜两种方法制备了ITO/MEH-PPV/Al结构的OLED器件。利用原子力显微镜、红外发射扫描电镜和紫外可见分光光度计对ITO薄膜的电学、结构和光学性质进行了研究。在680 nm范围内，ITO薄膜表面变得光滑，光致发光强度增加，从而改善了ITO薄膜与MEH-PPV之间的界面性能。
The interface between the electrodes and the organic layers in organic light emitting diodes (OLEDs) has been reported as playing an important role in in uencing their electrical and luminescent properties. Indium tin oxide (ITO) is commonly used as the anode material. The ITO thin lm has been deposited on glass substrate by radio-frequency (RF) magnetron sputtering and it has been used as an anode contact to fabricate an OLED device. The OLED devices with an ITO/MEH-PPV/Al con guration were fabricated by using both thermal evaporation and spin coating. We investigated the electrical, structural and optical properties of the ITO thin lm by using an atomic force microscope, a eld-emission scanning electron microscope and an ultraviolet-visible spectrophotometer. The interface property between ITO thin lm and MEH-PPV were improved as the surface of the ITO thin lm become smoothes and photoluminescence intensity was increased in the 680 nm range.
