fluorescence error

in spectrochemical analysis
https://doi.org/10.1351/goldbook.F02455
Some samples are excited to
fluorescence
by the incident radiation beam. When added to the transmitted radiation beam this
fluorescence
results in an erroneous
reading
called the
fluorescence
error. It is particularly noticeable if the photodetector is situated close to the sample.
