摘要

在这项工作中,研究了氧化铟锡(ITO)薄膜沉积在降解有机发光二极管(OLED)得到的玻璃衬底上的循环经济。在以前的工作中,这些装置是在实验室组装和极化的。每块衬底的几何尺寸为2.5 × 2.5 cm,分别设置了4个活性面积为3 × 3 mm的oled。这些OLED器件由ITO作为电极阳极和其他材料(逐层)的连续沉积组装而成,形成完整的结构。为了获得回收的ITO,从含有先前安装的oled的样品中去除所有层,只留下ITO薄膜,用商业产品和收到的ITO/玻璃样品一起清洗。使用比色法、电阻法和拉曼光谱等技术对两种样品进行了比较。采用发光二极管(LED)器件偏振发光光穿过ITO薄膜的方法,获得了具有色度坐标的亮度,揭示了薄膜具有良好的透明性。回收ITO的电阻比接收ITO的电阻高5个数量级。这一事实可归因于聚(苯乙烯磺酸盐)(PEDOT:PSS)层掺杂的聚(3,4-乙烯二氧噻吩)在oled组装过程中导致ITO薄膜腐蚀或四点探针电测量过程中产生的场线损失。拉曼光谱对样品的化学成分分析结果并不令人满意,但表明样品在分析前有良好的清洗过程。

Circular economy of ITO thin films deposited on glass obtained from degraded OLED devices
In this work, circular economy was investigated for commercial indium tin oxide (ITO) thin films deposited on glass substrates obtained from degraded organic light-emitting diodes (OLED). These devices were assembled and polarized at laboratory in a previous work. For each substrate, with geometry 2.5 × 2.5 cm, four OLEDs with active area of 3 × 3 mm were set up. These OLED devices were assembled with ITO as the electrode anode and successive depositions of other materials (layer-by-layer), to form the complete structure. To obtain the recovered ITO, all layers were removed from the samples containing the OLEDs previously mounted, remaining only the ITO thin films, that were cleaned with commercial product together with the received ITO/glass samples. Both samples were compared using some techniques, such as: colorimetry, electrical resistance, and Raman spectroscopy. A methodology with light-emitting diode (LED) device polarized emitting light crossing the ITO thin films was used, and the luminance with chromaticity coordinates was obtained, revealing the good transparency of the thin films. Electrical resistance of recovered ITO revealed five higher orders of magnitude in comparison to the one of received ITO. This fact can be tributed to a poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) (PEDOT:PSS) layer, causing corrosion of the ITO thin films during the assembly of OLEDs or loss of the field lines created during the electrical measurements by probes of four-point probe. Raman spectroscopy did not show satisfactory results in the chemical composition analyses of the samples, but it indicated good cleaning process of the samples before the analyses.
