Spectroscopy of Crystals Containing Rare Earth Ions

``Spectroscopy of Crystals Containing Rare Earth Ions'''' contains chapters on some key problems selected from a broad range of spectroscopic studies of RE-activated solids including both crystalline and glassy materials. Progress in crystal field theory is surveyed, an area which is basic to our understanding of the energy levels. The treatment of dynamical properties includes studies of cohere...
