fluorine
Properties of fluorine.
The term fluorescence was coined in 1852 and is derived from the mineral fluorspar (also known as fluorite).12
The name of the mineral itself originates from the Latin word fluere, meaning "to flow," as it has historically been used as a flux in metallurgical processes. The phenomenon was named after fluorspar because the mineral exhibits a distinct, short-duration luminescence when exposed to ultraviolet light.32
