We demonstrated a field emission lamp by employing a KMgF3 thin film as a solid-state vacuum ultraviolet phosphor. The output power of the lamp was 2 μW at an extraction voltage of 800 V and acceleration voltage of 1800 V, and it operated at wavelengths 140-220 nm, which is the shortest wavelength r...
