emission spectrum
n.
The spectrum of bright lines, bands, or continuous radiation characteristic of and determined by a specific emitting substance subjected to a specific kind of excitation.
emission spectrum
n
(Physics / General Physics) the continuous spectrum or pattern of bright lines or bands seen when the electromagnetic radiation emitted by a substance is passed into a spectrometer. The spectrum is characteristic of the emitting substance and the type of excitation to which it is subjected Compare absorption spectrum
emission spectrum
The distribution of electromagnetic radiation released by a substance whose atoms have been excited by heat or radiation. A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance's chemical or atomic composition. See more at atomic spectrum.

While the approximation of the peak height for the x-ray intensity measurement remains valid in most analytical problems with the EPMA, this simplified approach is no longer sufficient in the presence of severe peak overlaps as is the case for L emission spectra of rare-earth elements (1) or when soft x-ray emissions are used in the analytical procedure (2-4).
