Abstract

Abstract Some emission spectra of supported samples recorded with two experimental arrangements have been discussed. The existence is pointed out of a background emissivity which causes spectra with bands in relief to be recorded only in an optimum thickness range. The experimental behavior observed is in good agreement with the predictions based on some relationships here reported. Application of the latter to emissivity measurements is shown to supply optical constants consistent with the ones obtained by other techniques.
