02455 IUPAC Gold Book - fluorescence error 10.1351/goldbook.F02455 F02455 current 1 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. fluorescence https://goldbook.iupac.org//terms/view/F02453 reading https://goldbook.iupac.org//terms/view/R05189 PAC, 1988, 60, 1449.
