Time-resolved measurements of luminescence
In physics and physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques. Most often, processes are studied after the illumination of a material occurs, but in principle, the technique can be applied to any process that leads to a change in properties of a material. With the help of pulsed lasers, it is possible to study processes that occur on time scales as short as 10 seconds. All tim… WebWe report time-resolved measurements of photoluminescence in bulk a-${\mathrm{SiO}}_{2}$ using 7.9- and 6.4-eV excitation. Time-resolved spectra have been …

WebDec 8, 2024 · In addition, time-resolved fluorescence spectroscopy was conducted to investigate the fluorescence lifetime in the cocrystals. As shown in Figure 4 d, the fluorescence decay of the APE powders suspended in water shows a single-exponential decay with a lifetime of about 0.93 ns, while the fluorescence decay of the APE-TCNB … Measurements of luminescence lifetime hold inherent advantages over intensity …
WebPicosecond time-resolved measurements in glycerol showed that at least three excited states species of MLCT character are involved in the decay, and further that the populations are sensitive to hydrogen bonding which gives rise to an anomalous change in quantum yield with temperature. WebWe assessed the ability of luminescent quantum dots (QDs) to function as energy acceptors in fluorescence resonance energy transfer (FRET) assays, with organic dyes serving as donors. Either AlexaFluor 488 or Cy3 dye was attached to maltose binding protein (MBP) and used with various QD acceptors. Steady-state and time-resolved fluorescence …
