Only three standards can be considered well established. Another group of six standards has been investigated by several independent researchers. A large group of standards is frequently used in recent literature, but the validity of these is less certain. The needs for future development comprise: (i) confirmation of the validity of the QY values of many commonly used standard materials, preferably in the form of SI traceable standards; (ii) extension of the set of standard materials to the UV and near-IR spectral ranges; and (iii) good standards or robust protocols for the measurements of low QYs.

Photoacoustic imaging of fluorophores using pump-probe excitation

“…A minor adjustment of the quantum yield of R6G was found to improve the agreement between model and data, which is reasonable since the optical properties, such as the quantum yield, of most fluorophores are sensitive to environmental parameters, e.g. concentration, pH, oxygen saturation [40], and deviations from literature values on the order of a few percent are not uncommon [41].…”

Assembly of water-soluble chlorophyll-binding proteins with native hydrophobic chlorophylls in water-in-oil emulsions

“…Fluorescence yield was calculated by comparing the area under the emission band of each WSCP sample by that of Chl a in acetone, and assuming the yield of the latter to be 30% [26]. More specifically, the WSCP fluorescence yield, , is given by [27] where shape and position to the respective, previously reported spectra of native CaWSCP [17], BoWSCP [28], and LvWSCP [29]. An exception is the band at 468 nm that was observed only in the native complexes, and is attributed to the absorption of Chl b.…”

Synthesis and study on aroylhydrazones having cyanovinylpyrrole

“…For any photoluminescent species, the quantum yield (U F ) of its luminescence is a basic property, and its measurement is an important step in the characterization of the species. According to the definition of the U F (Brouwer, 2011), only two quantities need to be known, viz. the number of photons absorbed and the number of photons emitted per unit of time.…”
