Fig. 1 (a) Steady-state UV-Vis absorption and photoluminescence (PL) emission spectra obtained in degassed toluene at room temperature. (b) Time-resolved PL spectra recorded in a closed cryostat at ...

Although the fluorescence timescale is suitable for monitoring numerous biological processes, certain processes often require monitoring over extended durations. To access intrinsic amino acids, such ...

THE energy acquired by matter when it absorbs electromagnetic radiation is normally converted to heat, but in some cases much of the energy may be re-emitted as fluorescence or phosphorescence.
