Both cationic and anionic xanthene dyes are known to be efficient fluorescent dyes. Functional groups on the xanthene moiety control their fluorescent colors.
Applications of xanthene dyes involve optical materials and organic dyes for medical diagnosis research. Several characteristic features of xanthene dyes are large absorption and luminescence, excellent light resistance, low toxicity in-vivo, and relatively high solubility in water.
