A field emission lighting device and a method making the field emission lighting device are disclosed. The field emission lighting device includes a cathode, an anode, at least one emitter base, at least one conductive emitter tip, and a fluorescence layer. The emitter base is formed on the cathode and is made of diamond-like carbon. Each emitter tip is formed on a respective emitter base. The fluorescence layer is formed on the anode. In addition, each emitter tip has a bottom portion and a top portion. The bottom portion of the emitter tip has a cross-section size (i.e., diameter/width) essentially equal to the cross-section size of the emitter base. The emitter tip and the emitter base have a nanometer-magnitude size. The emitter base and a corresponding single emitter tip together form an emitter unit of the field emission lighting device.
