Abstract: In one embodiment of the present invention, an electron/photon source is disclosed based on field emission, cathodoluminescent and photo-enhanced field emission, including an evacuated chamber inside a housing, further including an anode and a cathode arranged inside the evacuated chamber. Furthermore, the cathode is arranged to emit electrons when a voltage is applied between the anode and cathode, the anode being arranged to emit light at a first wavelength range when receiving electrons emitted from the cathode, and a wavelength range converting material arranged to receive the emitted light of the first wavelength range and emit light at a second wavelength range. In a novel way, an embodiment of the present invention makes it possible to, in two steps, convert the electrons emitted from the cathode to visible light. The invention has shown to be advantageous, and makes it possible to select new emission materials, manufactured at a fraction of the cost associated with the earlier used materials where the electron to visible light conversion was done in one step.
