Iterative reconvolution towards function [Equation 1] yielded components of 5.47 and 6.6 ns. Relative amplitude of a first exponential falls down starting at 50 vol.% mixture, until relative amplitude inversion (longer exponential domination) happens at 60 vol.%. Overall, change in molecular environment causes 1 ns amplitude-weighted mean lifetime increase over the course of experiment (Figure ), probably due to aggregation and solvent-related non-radiative processes.
