Abstract

Photon generating devices produce predetermined radiation spectral output and heat for a variety of applications including lighting and electric power generation, and provide photons to enhance chemical and physical reactions. Such a device comprises an emitter which contains metal oxides, means to heat the emitter sufficiently to produce large number of photons of a desired spectral output, and an optical means for directing the photons to various targets. In one embodiment, the device includes a thermal input device, a light pipe having a low emissivity, and an emitter coating of superemitter material which is thermally stimulated to emit radiation of a specific wavelength above a threshold temperature. An intermediate layer may be used to bond the emitter coating to the light pipe or other optical device where desired. Another embodiment comprises coating blackbody emitters onto transparent optical waveguides, such as light pipes, and heating the coating to emit photons into the light pipes which are directed to a target, and further comprises a means to select a particular target.
