    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.
