The present disclosure generally relates to field emission cathode structure for a field emission arrangement, specifically adapted for enhance reliability and prolong the lifetime of the field emission arrangement by arranging a getter element underneath a gas permeable portion of the field emission cathode structure. The present disclosure also relates to a field emission lighting arrangement comprising such a field emission cathode structure and to a field emission lighting system.

Field emission cathode structure for a field emission arrangement

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.

Method for controllably growing ZnO Nanowires

The present invention relates to a method for the manufacture of a matrix and to a matrix ( ) thus manufactured, at least one surface section ( ) displaying a microstructure, which matrix ( ) is suitable for inclusion as a mould insert in a mould cavity or in a cavity, in a unit producing plastic components, in order to assign said plastic components an opposing micostructure in a corresponding surface section. An original ( ) with a surface section ( ) displaying a microstructure less than 500 &mgr;m is used in order to apply on this original layer upon layer of a material ( ) and/or mixtures of material producing a matrix, and thereafter the matrix ( ) is removed from said original ( ) or the material in the original is removed. A first layer of material ( ) applied on the original ( ) so that together with a number of additional layers of material, said matrix is formed, is selected having exceptionally good properties as regards the ability of the plastic component to release from the matrix after moulding, curing or polymerisation of the plastic material used, and exceptionally good properties as regards retaining the pattern on the microstructured surface section.
