Abstract:
1. A method for fabricating an electroluminescence (EL) device with a nanotip-contoured phosphor layer, the method comprising: providing a substrate with a planar top surface, made from a material selected from the group including silicon, glass, quartz, and plastic; forming a bottom electrode having a planar bottom surface overlying the substrate planar top surface, and a top surface with nanotips; forming a phosphor layer overlying the bottom electrode, having a bottom surface with a contour matching the bottom electrode nanotip contour, and a top surface with a contour matching the phosphor layer bottom surface contour; forming a contoured bottom dielectric interposed between the bottom electrode and the phosphor layer, having top and bottoms surfaces with contours matching the nanotip contour; and forming a top electrode overlying the phosphor layer.
