Abstract
Official abstract text for this publication.
Excimers are formed in a high pressure gas by applying a potential between a first electrode ( 14, 214 ) and a counter electrode ( 25, 226 ) so as to impose an electric field within the gas, or by introducing high energy electrons into the gas using an electron beam. A phosphor for converting the wavelength of radiation emitted from the formed excimers is disposed within the gas and outside a region ( 62, 162 ) where the excimers are expected to be formed, so as to avoid degradation of the phosphor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of generating light comprising: forming excimers within a chamber containing an excimer-forming gas and a phosphor by providing energetic free electrons within the gas, so that the excimers produce radiation and the radiation impinges on the phosphor, the step of providing energetic free electrons within the gas being performed so that in a region of the chamber a substantial majority of free electrons in the gas have energies equal to or grea…
