WebSolvent polarity and the local environment have profound effects on the emission spectra of polar fluorophores. These effects are the origin of the Stokes’ shift, which is one of the earliest observations in fluorescence. Emission spectra are easily measured, and as a result, there are numerous publications on emission spectra of fluorophores ... Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light. A complementary technique is absorp…
