Introduction:
The instrument of fluorescence spectroscopy, also called as Fluorimetry or spectrofluorometry, is a type of electromagnetic spectroscopy that analyzes fluorescence from a specimen. It includes using a beam of light, commonly ultraviolet light, that excites the electrons in molecules of specific compounds and causes them to emit light; usually, but not needful, visible light. A finished technique is absorption spectroscopy. Both fluorescence and phosphorescence are examples of photoluminescence (luminescence).
Luminescence is that process of making reemission of previously absorbed light while the molecules that in the ground state absorb UV light. The molecules are transferred to the excited state, then, they reemission of the formerly absorbed light takes place and the molecules return back to the ground state where fluorescence or phosphorescence takes place.
On the other hand there were a molecular emission, so after the absorption of UV Visible light, the excited molecular types are really very short-lived and deactivation occurs due to:
Internal collision ,internal conversion, or to cleavage of chemical bonds begin photochemical reactions, or because a re-emission of light (luminescence), or maybe due to heat and lastly may is due to an interaction between a solute and the solvent molecules on an excitation ordinarily …show more content…

First of all it is important to understand the science and theory behind fluorescence to be able to understand how a spectrofluorometre works. Fluorescence is a phenomena that happens when a molecule absorbs light in a specific wavelength and then eremite it in another wavelength. The time required for the whole process of fluorescence to happen is very short, it is estimated to be about 10-7 seconds or less, which is a very useful property because it can then provide information about processes that happen in extremely short
