Abstract
AbstractIndium tin oxide (ITO) is a transparent conducting material that is widely used in devices where high transparency of the electrodes is required, such as flat panel and liquid crystal displays, touch panels, smart windows, and many others. ITO layers are deposited on a large scale by magnetron sputtering and then structured by lithography to define desired patterns of transparent electrodes. Here, a method for direct printing of transparent conductive patterns from ITO nanoparticle ink is communicated. The method combines inkjet printing with fast flash lamp annealing whereby the main novelty is to use an additional layer of a colored organic dye onto printed ITO to increase light absorption. The dye coating is instantly heated together with the underlying ITO layer by a light pulse, leading to an instant rise of the surface temperature, which is translated into improved optoelectronic properties of the ITO layers. Inkjet‐printed ITO patterns processed with the dye‐assisted flash lamp annealing exhibit a transmittance of up to 88% at 550 nm and resistivity of 3.1 × 10−3 Ω cm. Transparent touch‐sensing trackpad and capacitive touch sensors are demonstrated based on the printed ITO patterns, which can be utilized in transparent security systems and other transparent Internet‐of‐Things devices.

Among various Transparent conducting oxides (TCOs) mate- step is crucial for improving the layer density and composition rials, indium tin oxide (ITO) is the most prominent due to its low that enables high carrier mobility.[24,25]
Summary
Indium tin oxide (ITO) is a transparent conducting material that is widely on an industrial scale to fabricate high-perused in devices where high transparency of the electrodes is required, such as flat panel and liquid crystal displays, touch panels, smart windows, and many others. The dispersion of a blue organic dye (Sensidizer SQ2) in ethanol is spin-coated onto the ITO film (Figure 1c). ITO film with the dye layer is processed with FLA (Figure 1d).
