A Field Emitter Device (FED) having a substantially reducing atmosphere is described. The atmosphere in a FED can be maintained substantially free of oxidizing gases and includes a partial pressure of hydrogen between about 1.times.10.sup.-7 millibar (mbar) and 1.times.10.sup.-3 mbar. In one embodiment, a non-evaporable getter material previously charged with hydrogen gas is placed inside the FED before the FED is sealed. The non-evaporable getter material can be charged by exposure to hydrogen gas at a pressure between about 1.times.10.sup.-4 and about 2 bar. Subsequently, the components forming the FED are sealed, and the FED is evacuated and hermetically sealed to the outside atmosphere.

[ What is claimed:] [1.] A field emitter device, comprising:a) first and second planar portions sealably joined along their perimeters, said first and second planar portions having opposing interior surfaces defining an interior space;b) a non-evaporable getter material, localized at a discrete position in said interior space, charged with hydrogen in fluid communication with said interior space, said non-evaporable getter material being effective to release hydrogen gas into said interior space to provide thereby a substantially reducing atmosphere in said interior space; andc) a heater for regulating the temperature of said non-evaporable getter material to control thereby the amount of hydrogen released into said interior space, said heater located proximate to said non-evaporable getter and on at least one of said interior surfaces of said first and second planar portions.
