Raman spectra of rhodamine 6g

WebbWe have investigated the absorption and fluorescence spectra of Rhodamine 6G thin (20-100 nm) films vacuum-deposited on solid dielectric substrates: quartz and borosilicate glasses and polymer films. WebbRhodamine 6G (R6G) is an organic laser dye and can be used to study the probes as it has a high quantum yield for fluorescence. It can be used as a fluorescence tracker which helps in defining the spectroscopic characteristics for achieving a high conversion efficiency and precision of measurements.
