Luminescence dating definition

Karl Karlovich Rebane has written: 'Hot luminescence and relaxation processes in the centres of luminescence' -- subject(s): Luminescence, Relaxation (Nuclear physics) 'Energia, entroopia, elukeskkond' -- subject(s): Entropy, Environmental protection, Power resources A substance that increases the effectiveness of a rubber vulcanization accelerator; for example, zinc oxide or litharge.

A trace quantity of a substance that imparts luminescence to crystals; for example, silver or copper in zinc sulfide or cadmium sulfide pigments.

The term 'luminescence' was introduced in 1888 by Eilhard Wiedemann.

The other types are luminescence is chemiluminescence, electroluminescence, electrochemiluminescense, photoluminescense, thermoluminescence, and thermoluminescense.

Thermoluminescence (TL) is the process in which a mineral emits light while it is being heated: it is a stimulated emission process occurring when the thermally excited emission of light follows the previous absorption of energy from radiation.

Energy absorbed from ionising radiation (alpha, beta, gamma, cosmic rays) frees electrons to move through the crystal lattice and some are trapped at imperfections in the lattice.
