[WP4-D3] Screen-Printed Titania Nanocomposite for Efficient Light Extraction in Organic Light Emission Device
キーワード：Novel photonic materials for active devices, Advanced Active Devices
In this work, we apply screen-printed method for light extraction layer fabrication for an organic light-emission diode. Screen-printing is a large-area, solution-processed, and low cost, which is appropriate for volume production in organic lighting application. With TiO2, the interfaces between glass substrate to the air were modified. The high refraction index of TiO2 cause the light could be extracted smoothly at glass/TiO2 interface. By incorporating screen-printed TiO2 nanocomposite, the luminescence efficiency enhanced over 65%.
