7. The fluorophore lifetime of DMADHC was determined on a FLS-920 Combined fluorescence lifetime and steady state spectrometer (Edinburgh, UK). A Picosecond diode laser of 405 nm was chosen as the source for the fluorescence lifetime determination. Both the excitation and emission slit widths were 1.20 nm. The average fhiorophore lifetime of DMADHC was 2.05 ± 0.01 ns by repeatedly measuring six times.
