An ultraviolet light-induced photophysical and photochemical study of laser-dye rhodamin-610 and its photoproduct in solution

In this work an ultraviolet light-induced photophysical and photochemical changes of rhodamin-610 in ethanol have been studied by photolysis technique at room temperature, due to its potential applications in photonics, photochemistry and electronic spectroscopy. During the optical pumping, rhodamin-610 showed photochemical changes, therefore as the concentration of rhodamin-610 decreased, a photoproduct concentration increased rapidly. An absorption band of the product was observed at around 300 nm. photoproduct emission spectra characteristics show that photoproduct molecules can also be used as a laser-dye at different emission frequency
