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.
