Spectrofluorimetry or simply Fluorometry is a technique which uses the measurement of the intensity of fluorescent light emitted by substance to be examined in relation to that emitted by a given substance. It is a widely used photoluminescence method in analytical chemistry and is ideal for analysis of small quantities (in microgram) of fluorescent materials particularly where interference in UV-vis spectrometry is a major analytical constrain. It has high sensitivity, selectivity and is most preferred spectrometric assay method for a number of chemical substances including food, and drugs. The success of quantification and its reliability using the method rely solely on the intensity of the fluorescent light emitted by the sample solution and detected at the detector. In this article, critical review of the factors influencing fluorescent intensity including quantum yield, intensity of incident light, path length, adsorption, oxygen, pH, photodecomposition, temperature, viscosity, scatter and quenchers were attempted.
