ing solids: deviations from perfect order have been treated as perturbations of the ideal model. A new situation arises with truly disordered solids where any vestige of long range order has disappeared. The basic problem is that of describing these systems and gaining a scientific understanding of their phys978-1-4684-5477-2978-1-4684-5475-8

Sharp Spectral Lines of Luminescent Centers in Solids, broadening due to the spatial randomness. In glasses this randomness may represent the prevalent cause of broadening even at room temperature and may produce lines as wide as 100 cm.for rare earth centers. Inhomogeneous broadening may have relevant effects on the spectral characteristics of a syste

There are a number of unexplained results for concentrations above percolation

Effects of Disorder on the Spectral Properties of Cr-Doped Glasses, Glassceramics and Crystals,roperties and the optical properties of Cr.-doped compounds have to be studied not only for basic research reasons but also for applications in lasers and luminescent solar collectors. In this course we will see a few examples of Cr.-doped different host networks like oxide glasses, spinel-type glas

Physics and Spectroscopy of Laser Insulating Crystals with Disordered Structure,results among which are new low-temperature measurements on the spectroscopy of stimulated emission of Nd. ions on different disordered fluorine-and oxygen-containing crystals are presented to illustrate these objective principles. New data on record laser-wavelength tuning of octahedral Cr. ions in

Probabilistic Methods in Physics,distribution into another. Hence for every application some a priori distribution must be defined on the basis of the underlying physics. The mere use of the word ‘random’ is not enough, particularly since that word is often used in the sense of ‘irregular’ or ‘disordered’. The transition of a disor
