fluorescent yield

Addition of biacetyl does not markedly reduce the fluorescent yield, while addition of cyclohexane, CO2, and cis-butene-2 causes an increase in the fluorescent yield.

Soft x-ray absorption spectra are usually measured either through the fluorescent yield, in which emitted photons are monitored, or total electron yield, in which the sample is connected to ground through an ammeter and the neutralization current is monitored.
