Eosin Y - omlc.org
The fluorescence emission spectrum of Eosin Y dissolved in basic ethanol. The excitation wavelength was 490nm. The quantum yield of this molecule is 0.67 (Seybold, 1969b).
Effect of Solvent on Intensity of Absorption and Florescence of Eosin Y Dye and Spectral Properties of Eosin Y Dye. In this pepar, the effect of concentration on the fluorescence and absorption spectra of Eosin yin (ethanol, methanol, and DMF) atconcentrations [1×10-4M] and [1×10-5M] was studied.
Eosin fluorescence: A diagnostic tool for quantification of liver ...
2017年9月1日 · In this study we have shown that under pathological conditions, eosin fluorescence can be used to quantify damage to a tissue. The change in the fluorescence spectrum of eosin is due to differential binding ability of eosin to denatured protein under pathological conditions.
Laser induced fluorescence spectroscopy of aqueous eosin Y …
2024年3月1日 · Fluorescence inner filters (IFs) of Eosin Y (EY) solution were assessed. LIF accomplished under conditions with the least photo-degradation effect. Monomers, dimers and higher aggregates determine LIF emission profile. IFs depend on excitation wavelength, EY concentration and detection geometry.
