^aλ, ε, and τ are given in nm, 10³ M⁻¹cm⁻¹, and ns respectively

^bData from Bachilo et al.¹⁶⁸ and Cundall et al.¹⁶⁹

^cε is given only for the most intense λ_abs.¹⁷⁰

^dλ_em, Φ_fl and τ are from Hermetter.¹⁴²

^eλ_abs is extracted from a graph, λ_em is highly solvent polarity sensitive, several values for λ_em and τ have been reported, some of which are contradicting.¹⁵⁴
