Abstract

An experimental study of a fluorescent broadband light source fully compatible with optical fibers is presented in the article, with the aim of using it for excitation-emission matrix fluorescence spectroscopy. A fiber optic glass ferrule filled with a solution of Rhodamine 6G in glycerin was used for the basic construction of the light source. The ferrule is coupled with optical fibers to illuminate the dye medium and to receive the fluorescent signal. A tuning of the light spectrum from the source between 528 nm and 660 nm with a shift of 1 nm is achieved by means of a monochromator.
