NUMERICAL SIMULATIONS OF THE STRUCTURE AND SPECTROSCOPIC PROPERTIES OF RARE-EARTH-DOPED GLASSES

A review of the research that has been devoted to the simulation of th e structure and spectroscopic properties of rare-earth doped glasses i s presented. Since the seminal papers of Brawer and Weber who have app lied Monte-Carlo or molecular dynamics techniques, some other very imp ortant results have been reported concerning the local structure of th e dopants. As a result, crystal field models have been applied and sev eral pecularities of the optical spectra of rare earth ions in glasses have been understood.
