    摘要： An electron field-emission display comprises one or more display cell structures, each having a field-emission cathode and an anode comprising at least one of several cathodoluminescent phosphors disclosed which are stimulable by electrons of very low energy. The display cell structures may also have gate elements for controlling electron current flowing from cathode to anode when suitable electrical bias voltages are applied. A preferred fabrication process integrates an etch stop with an in situ phosphor formation process. The etch stop precisely defines the depth of an opening in the display cell structure. Metal oxides or mixed-metal oxides of zinc, copper, tin, or indium are heated in the presence of a refractory metal such as titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, or combinations thereof to make phosphors of various chromaticities, which may also include dopants, such as a lanthanide rare earth element, manganese, chromium, or stoichiometrically excess zinc, copper, tin, or indium. A blue-light-emitting phosphor embodiment is based on ZnO treated with refractory metals, e.g. Ta, to prepare cathodoluminescent phosphor compositions, e.g. Ta.sub.2 Zn.sub.3 O.sub.8. Selective arrangement of various color phosphors may be made by selective deposition of suitable dopants. The selective deposition may be done, e.g. by chemical vapor deposition with appropriate masking, or by selective ion implantation.

    摘要： An electron field-emission display comprises one or more display cell structures, each having a field-emission cathode and an anode comprising at least one of several cathodoluminescent phosphors disclosed. The display cell structures may also have one or more gate elements for controlling electron current flowing from cathode to anode when suitable electrical bias voltages are applied. A cell may have more than one phosphor, and in particular may have red, green, and blue phosphors selectively arranged. Each pixel site may have one anode of each color phosphor. The phosphors are preferably prepared in situ in an electrically-conductive thin-film or surface-layer form during fabrication of the display. A preferred fabrication process integrates an etch stop with the in situ phosphor process, the etch stop precisely defining the depth of an opening in the display cell structure. Metal oxides or mixed-metal oxides of zinc, copper, tin, or indium are heated in the presence of a refractory metal such as titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, or combinations thereof to make phosphors of various chromaticities, which may also include dopants, such as a lanthanide rare earth element, manganese, chromium, or stoichiometrically excess zinc, copper, tin, or indium. The display is operable when its phosphor is excited by electrons of very low energy.
