Abstract: The present invention relates to a field emission lighting arrangement, comprising an anode and a cathode, where the shape of the cathode is selected based on the shape of a evacuated envelope in which the anode and cathode is provided. The inventive shape of cathode allows for an improved uniformity of an electric field provided between the anode and cathode during operation of the field emission lighting arrangement. The invention also relates to a corresponding method for selecting a shape of such a cathode.

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 relates to a method for controllably growing ZnO nanowires, for example to be used in relation to field emission lighting. In particular, the invention relates to a method of controlling thermal oxidation conditions to achieve steady-state conditions between an oxygen consumption rate by a growing oxide on a surface of a structure and the decomposition rate of the oxygen-carrying species within the chamber. The invention also relates to a corresponding field emission cathode.
