Read more is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid.We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g.Luminescence dating is based on the perception in solid state physics that energy from the absorption of ionizing radiation can be stored in the crystal lattice of insulators as radiation damage.Thermal or optical stimulation of dosed mineral grains results in release of radiation-induced luminescence.The present contribution deals with the history of luminescence dating from the first observations of the luminescence phenomenon via the first proposal to use it for dating purposes, and the first dating application to the present wide field of applications in archaeology, Quaternary geology, geomorphology and geoarchaeology.Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold body radiation.
Assuming a constant rate of natural ionizing radiation the age is calculated as the ratio of the accumulated dose over the dose-rate.coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome.Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest.To put it simply, certain minerals (quartz, feldspar, and calcite), store energy from the sun at a known rate.This energy is lodged in the imperfect lattices of the mineral's crystals.It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal.
