1. A method comprising:
mixing a first getter material with a second getter material to create a mixed evaporable getter material;
mixing an oxide dopant with the mixed getter material to create a doped evaporable getter material;
sealing the doped evaporable getter material within a device; and
applying heat to the doped evaporable getter material to cause the doped evaporable getter material to emit a doped gas for deposition on internal surfaces of the device.
