General description

Rhodamine 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. The absorption of R6G in different solvents can range between 400-700 nm.


R6G can be used as a cationic dye to determine the photocatalytic ability of TiO2 reinforced graphene oxide composites that can be potentially used in self-cleaning applications. It can be used to calculate the quantum yield of glutathione-capped copper nanoclusters (CuNCs) for fluorescent thermo-responsive nanomaterials and gold nanoparticles (AuNPs) for fluorescent/X-ray computed tomography.
