Rhodamine B is a type of amphoteric dye that is frequently employed as a fluorochrome. It is an organic chloride salt and a xanthene dye. As the temperature rises, there is a corresponding drop in the fluorescence intensity of rhodamine B.
Rhodamine B is capable of coexisting in equilibrium as both its “open” or fluorescent form and its “closed” or nonfluorescent spirolactone form. When exposed to an acidic environment, the “open” form predominates, whereas the “closed” form is colorless and predominates when exposed to a basic environment.
