Silver nanowire (Ag NW) electrode-based AC powder electroluminescent device (ACPELD) is demonstrated. Ag NW electrode with the transparency of 90 % and sheet resistance of 50 ohm/sq was bar-coated, and the phosphor/dielectric layers were screen printed. The EL intensity and charge density were as high as that for ITO-based ACPELD. 1. INTRODUCTION Alternating current powder electroluminescent devices (ACPELDs) have a high potential for commercial application, because of their high resolution and brightness, uniform light emission, and low power consumption together with the possibility of a thin architecture (60-100 μm). ACPELDs can be used in liquid crystal display backlight such as cellular phones and personal digital assistants and also in large-scale architectural and decorative lighting [1]. Up to now, transparent conducting oxides such as indium-tin oxide (ITO) electrodes prepared by cost-intensive sputtering techniques constitute the electrode through which the light is extracted. However, low-temperature deposition techniques compatible with flexible polymer substrates lead to higher sheet resistances and surface roughness of the ITO electrode. Moreover, repeated bending of ITO electrodes causes cracking and delamination limiting their flexibility. Referring to these facts and the extremely increasing demand on indium and leading to a strong price advance, transparent silver nanowire (Ag NW) electrodes seem to be a valuable alternative for ITO-based electrodes for applications with moderate requirements on conductivity. Here we report the fabrication of highly efficient blue-green ACPELDs based on the silver nanowire (Ag NW) electrode.
