This book presents the recent advances in spectroscopy and theoretical modeling relevant to the interpretation of luminescence and laser phenomena in solid state materials. The available solid state matrices in crystalline and glassy states and the full range of activaters-transition metal ions, rare earth ions and actinides are considered here. Processes of activator excitation, energy transfer between activators and relaxation of excited states are particularly stressed.
