Cold emission electrode method of manufacturing the same and display device using the same
摘要:
An yttrium film is formed on the surface of a substrate made of an Ni—Cr-based material by deposition or sputtering using resistance heating or an electron beam. The yttrium film is heated in an inert gas atmosphere containing a very small amount of hydrogen to hydrogenate yttrium. The resultant yttrium hydride is excellent as a cold emission material for a cold emission electrode and can be used for a cold emission discharge fluorescent tube.
