TL;DR: This work compares and evaluates the differences in physicochemical properties of common fluorescent labels, focusing on traditional organic dyes and QDs, to provide a better understanding of the advantages and limitations of both classes of chromophores.

TL;DR: This protocol describes procedures for relative and absolute determinations of Φf values of fluorophores in transparent solution using optical methods, and introduces a series of eight candidate quantum yield standards for the wavelength region of ∼350–950 nm.

TL;DR: In this article, the authors investigated achievable uncertainties for the determination of fluorescence quantum yields of these chromophores and illustrate common pitfalls exemplarily for differently sized water-soluble CdTe QDs.

TL;DR: This work compares two relative and one absolute fluorometric method for the determination of the fluorescence quantum yields of quinine sulfate dihydrate, coumarin 153, fluorescein, rhodamine 6G, and rhodamines 101, thereby providing evaluated standard operation procedures for Φ(f) measurements and, simultaneously, a set of assessed Φ (f) standards.

TL;DR: Prevention of back-intersystem crossing from the (2)E to the (4)T2 state enables exceptionally high near-infrared phosphorescence quantum yields and lifetimes for this 3d metal complex.
