The parameters result from their log-normal Gaussian deconvolution (see Materials and Methods). Quantum yield (QY) was calculated taking 1,1,4,4-tetraphenylbutadiene in cyclohexane as the reference compound (quantum yield of 0.60; Berlman, 1971). The QY for each emitting species is the QY for total emission weighted by the emitting surface spectrum of that species. A sum of three elemental log-normal Gaussian curves (see Materials and Methods) was used for the deconvolution.
