Methods of controlling the brightness of a glow discharge

A plasma processing device is described which is modular and can be scaled up by assembly together with similar devices to provide a capability for large area processing. The device includes a housing which contains an array of RF coils and into which a process gas is fed. The article to be processed is disposed close to the housing and egress of the process gas from the housing to the process region is resisted so as to maintain a positive pressure differential between the housing and the process region.

An electroluminescent device comprises a film containing a phosphor. Means for causing movement of electrons in the film comprising a first layer on one side of the film and a second layer on the other side of the film are provided. The film includes a first material which is also present in the first layer. It has been noted that such a device has enhanced luminescence as compared to a conventional electroluminescent device.
