Abstract

An infrared radiation emitting element is provided. A carbonized conducting filament is formed from an insulating substrate material. Passing current through the filament produces radiation in the infrared band. The radiation emitted is tuned by altering the physical or chemical characteristics of the filament. A substrate is optionally doped prior to filament formation. Alternatively, or in addition, a post-filament formation doping process is used. The light-emitting element is a durable, low power IR emitter that is operable as a marker.
