A device and a fabrication method are provided for an EL device with a nanotip-contoured phosphor layer. The method comprises: forming a bottom electrode with nanotips; forming a phosphor layer overlying the bottom electrode, having irregularly-shaped top and bottom surfaces; and, forming a top electrode overlying the phosphor layer. The bottom electrode top surface has a nanotip contour, and the phosphor layer irregularly-shaped top and bottom surfaces have contours approximately matching the bottom electrode top surface nanotip contour. In one aspect, a contoured bottom dielectric is interposed between the bottom electrode and the phosphor layer, having top and bottoms surfaces with contours approximately matching the nanotip contour. Likewise, a top dielectric may be interposed between the top electrode and the phosphor layer, having a bottom surface with a contour approximately matching the contour of phosphor layer top surface.
