Viewable images may be displayed from a substantially dark substrate. Light emitting material may be integrated into a substantially dark substrate. The light emitting material may be configured to emit visible light in response to absorption of ultraviolet light. The light emitting material may include a plurality of light emitting particles and each of the plurality of light emitting particles has a diameter less than about 500 nanometers. For example, emitting visible light from a substantially dark substrate may allow for images to be displayed with relatively high contrast. These high contrast images may appear clearer to a viewer and may result in less eye strain by a viewer.
