摘要:
The present invention relates to a field emission light source die configured to emit UV light and a method for forming such a field emission light source. The field emission light source comprises a field emission cathode (106) comprising a plurality of ZnO nanorods (104) formed on a wafer, an electrically conductive anode structure (108) comprising a wavelength converting material (118) arranged to cover at least a portion of the anode structure, and a circular or elliptical spacer structure (110) for forming an hermetically sealed and evacuated cavity (306) between the substrate of the field emission cathode and the anode structure.
摘要:
There is provided a method for manufacturing a plurality of nanostructures comprising the steps of providing a plurality of spherical Zn structures and oxidizing the spherical structures in ambient atmosphere at a temperature in the range of 350° C. to 600° C. for a time period in the range of h to 172 h, such that ZnO nanowires protruding from the spherical structures are formed. There is also provided a field emission arrangement comprising a cathode having the aforementioned ZnO nanowire structures arranged thereon.
