^a from ref [34]

^b calculated (with QY = Brightness/ε) based on ref [23]

^c according to ATTO-TEC

^d based on our own QY-measurement of DOTA-complexes

^e according to the manufacturer

^faccording to absorption spectra by Carnall [35]

^g calculated from ThermoFisher Scientific SpectraViewer [36] as percentage from the ε_max

^h based on our own absorption measurement of Eu and Tb acetates in water.
