Luminescence of minerals
- the phenomenon of the glow of minerals in ultraviolet rays. The reasons for luminescence are as follows: when a photon hits the atoms of the crystal lattice, its energy is transferred to them. This leads to a change in the oscillation frequency at the nodes of the crystal lattice. Keep in mind that the energy of UV radiation is stronger than ordinary light. As a result, the ions change their location.
Luminescence is divided into two types:
- a phenomenon in which the sample returns to its previous state almost immediately after the cessation of irradiation,
- a phenomenon in which the sample continues to glow for some time after the cessation of irradiation with UV light. The fading of the glow can last up to several hours.
