Fluorescence standards: Classification, terminology, and recommendations on their selection, use, and production (IUPAC Technical Report)

Chromophore-based fluorescence standards for the characterization of photo-luminescence measuring systems and the determination of relevant fluorometric quantities are classified according to their scope and area of application. General and type-specific requirements for suitable standards are derived for each class of standards. Metrological requirements linked to the realization of comparable measurements are addressed and recommendations on selecting, using, and developing fluorescence standards are given.
