    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: The present invention generally relates to a system for treating a fluid and specifically to a treatment system (200) configured for selectively activating a first (206) and a second UV light source (104). The aim of the invention is to reduce the effective energy consumption of a system for treating a fluid with UV light. The invention especially concerns to overcome the drawback with mercury light sources, which do not turn on immediately. Only the second UV light source (104) is an UV mercury based light source and the electrical power supply is configured to selectively deactivate the first UV light source (206) based on a predetermined condition based on a warm-up period for the second light source.
