Abstract
Robust, large area selective infrared line emitters can be made using composites of rare earth metal compound particulates dispersed and interlocked in a network of connected structure-forming fibers having an emissivity less than about 0.1 in the range 0.7-5 microns. Articles where the composite is formed of rare earth metal oxide fibers in a network of sinter-bonded quartz fibers show narrow bandwidth emissions with good thermal conversion efficiencies.
