Abstract: The present invention relates to the field of field emission lighting, and specifically to a method for forming a field emission cathode. The method comprises arranging a growth substrate in a growth solution comprising a Zn-based growth agent, the growth solution having a pre-defined pH-value at room temperature; increasing the pH value of the growth solution to reach a nucleation phase; upon increasing the pH of the solution nucleation starts. The growth phase is then entered by decreasing the pH. The length of the nanorods is determined by the growth time. The process is terminated by increasing the pH to form sharp tips. The invention also relates to a structure for such a field emission cathode and to a lighting arrangement comprising the field emission cathode.

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.
