Novel Materials for Power Systems. Part 3. Selective Emitters for Energy Conversion
Abstract
The purpose of the research was to determine those materials which would be most promising for use as selective emitters, to fabricate initial samples for testing, to build an optical system capable of measuring the spectral efficiency rapidly, and accurately, and to make initial measurements on the spectral efficiency of promising samples. All of these goals have been met. It has been determined that the rare earth oxides and mixtures of rare earth oxides are quite promising as selective emitters for energy conversion. Initial samples of erbium oxide and mixtures of erbium oxide and ytterbium oxide have been fabricated. An optical system for measuring spectral efficiency has been built and preliminary tests run for measuring the spectral efficiency of these materials. The spectral efficiency measurement apparatus incorporates an automatic data acquisition system which allows the rapid processing of large numbers of samples.
