Reference Materials for Fluorescence Based on Inorganic Glass

Reference materials (RM) for relative spectral correction of emission spectra and day-to-day sensitivity monitoring of spectrofluorimeters were developed. The 2 kinds of inorganic glass were used as RM material – custom developed Cu+ –ion doped phosphate glass and colored optical glass SZS-17 (blue-green). RM can be either cuvette-shaped or in the form of flat plate and installed in sample compartment of the instrument. Flat plate geometry allows to minimize the dependency of RM fluorescence intensity from the characteristics of instrument's optical circuit due to inner filter effect.
