Abstract
Primary emphasis was placed on electrophoretic deposition of the low‐voltage phosphor to the indium‐tin oxide coated glass for the application of field emission display. The suspension was prepared with ZnS:Cu, Al green phosphor, isopropyl alcohol, nitride, and glycerin. The phosphor deposited by various parameters, such as deposition time and applied voltage, was examined in detail. In addition, a comparison was made by analyzing luminance properties of the phosphor mixed with and without the conducting powder of less than 1 μm size. The measurement was performed as a function of concentration from 3 to 15 wt %. The enhanced impact of the indium powder mixing on the phosphor was clearly demonstrated by the aging performance curve at 1000 V excitation voltages with a current density of . The optimum mixing concentration of the powder was 10% in this investigation. © 2000 The Electrochemical Society. All rights reserved.
