A plastic electrode transparent is important to flexible optoelectronic devices. The metal oxides are coated in plastic by a variety of methods. The temperature in the process will not exceed 100 °C-150 °C or room temperature. It causes cracking on the film, adhesion on the plastic surface, and impurities on the film. Therefore, plasma oxygen was used to improve the film. In this work, we fabricate plastic electrode transparent with indium titanium oxide (ITiO) film using oxygen (O 2 ) plasma treatment. ITiO film was deposited on polyethylene terephthalate (PET) using the RF magnetron sputtering method. The obtained ITiO PET films were plasma treated with O 2 using the plasma enhanced chemical vapor deposition system at plasma power and plasma treatment time condition. The structural properties and crystalline of ITiO film were confirmed by X-ray diffraction by scanning electron microscope and atomic force microscope. The high transmittance of ITiO films was about 80%-86% of all plasma treatment conditions. The lowest resistivity of the ITiO films with plasma treatment by plasma power condition and plasma treatment time was 7.92 × 10 -1 Ω-cm of 300 W plasma power and 7.81 × 10 −1 Ω-cm of 300 W plasma power, respectively. The luminance properties and EL efficiency of ITiO PET film was 89.21 cd m −2 and 0.0365 lm W −1 for a 60 min treatment time, 72.42 cd m −2 and 0.0297 lm W −1 for plasma power. The use of ITiO on a PET film by oxygen plasma treatment can improve the performance of the display device.

Electroluminescence (EL) device is a new technology; its thickness is within micrometer range which can bend more easily and emit light. However, the thickness of ZnS:Cu phosphor layer may affect the light intensity, so we have analyzed the thickness of ZnS:Cu phosphor layer on EL device. The EL devices consist of ITO:PET/ZnS:Cu phosphor/insulator (BaTiO 3 )/Ag electrode. The EL devices were fabricated in changing thickness 10 μm, 30 μm, and 50 μm. At 100 V 400 Hz, the luminance of EL devices was 51.22 cd/m 2 for thickness 30 μm more than that of 45.78 cd/m 2 (thickness: 10 μm) and 42.58 cd/m 2 (thickness: 50 μm). However, the peak light intensity was achieved at wavelength of 507 nm which was not influenced by the thickness of the ZnS:Cu phosphor. The use of the ZnS:Cu phosphor layer at thickness 30 μm in the EL device significantly improves the luminescence performance.
