Fluorescence is a property not a mineral.

Fluorescence is visible after UV irradiation; some substances as phosphates enhance the uranium fluorescence. Other substances can quench the uranium fluorescence.

The principle of fluorescence spectroscopy is the interaction with light image.

The fluorescence in a mineral is where it will shine or reflect under a ultraviolet light.

Fluorescence occurs when a substance has absorbed light and later emits that light. Quartz is a material that undergoes this process. Minerals and creatures can both exhibit fluorescence.
