WebSamples were also diluted in saline containing 10% FBS to confirm aggregation and precipitation in solvent mixtures. Absorbance and fluorescence emission spectra of the series of NIR fluorophores were measured using fiber optic HR2000 absorbance (200– 1100 nm) and USB2000FL fluorescence (350–1000 nm) spectrometers (Ocean Optics, … WebAs a biochemist, I use fluorophores daily but I've realized I don't entirely understand the underlying physics. If fluorescence is a result of excited electrons emitting photons, why are emission spectra shown as continuous? Shouldn't only certain emission wavelengths be allowed based on electron energy states?

The range of wavelengths within which excitation and emission occur are referred to as the excitation and emission spectra. The fluorophore absorbs light energy of a specific wavelength and re-emits light at a longer wavelength. The absorbed wavelengths, energy transfer efficiency, and time before emission depend on both the fluorophore structure and its chemical environment, as the molecule in its excited state interacts surrounding molecules. Wavelengths of maximum absorption (≈ excitation) and emission (for example, Absorption/Emission = 485 nm/517 nm) are the typical terms used t… iris and sodium shader packs
