Fluorescence Spectroscopy for Studying Evaporating Droplets Using the Dye Eosin-Y

Abstract: Laser-induced fluorescence (LIF) spectroscopy using dyes is frequently applied for characterization of liquids and two-phase flows. The technique is utilized e.g., for mixing studies, thermometry, or droplet sizing. One major application of the LIF technique combined with Mie-scattering is the planar measurement of droplet sizes in spray systems. However, its uncertainty is determined, among others, by varying dye concentration and temperature changes occurring during mixing and droplet evaporation. Systematic… Show more

“…Radical species generated by EY triggered by LED light are transferred to the methacrylamide and methacrylate groups of GelMA, leading to the covalent bonding of residual groups and subsequent crosslinking [39]. However, the absorption spectrum of EY is known to undergo slight variations depending on its concentration and temperature, and the emission spectrum of LEDs is also known to be influenced by the applied voltage [42,43]. Figure 2(A) shows that the absorption spectrum of EY (blue) and the emission spectrum of the LED (green) were measured, and both had peaks at 520 nm.…”
