Laser-induced fluorescence is the process of exciting molecules or atoms to a higher energy state through the absorption of laser light. The excited molecules decay after a short time (nano- to ...

real-time imaging of laser-induced fluorescence (LIF) from PAHs and laser-induced heating (LIH) from soot particles, along with elastic light scattering (ELS) from laser-soot interactions.

Figure 3 shows the TA and fluorescence spectra obtained from rose bengal in acetonitrile. TA was used to measure the ...
