Fluorescence Properties of Twenty Fluorescein Derivatives: …

WebJun 19, 2024 · Fluorescence radiation has its own characteristic spectrum whose intensity depends on the intensity and wavelength of the excitation radiation. In our measurements we used a fixed wavelength excitation source and we used the TO spectrometer to record the emission spectrum. WebFirst, look at the spectra of the three dyes. Fluorescein in water absorbs blue and purple light, with the maximum absorbance at 490 nm. It does not absorb red light, and it only absorbs some yellow and green light. Consistent with this, solid fluorescein is red, and fluorescein solutions are usually yellow to green. flower shops west des moines
