Energies of Rare-Earth Ion States Relative to Host Bands in Optical Materials from Electron Photoemission Spectroscopy: Author: Thiel, Charles Warren; Date: 2003-12-15; Program: Physics; Abstract: There are a vast number of applications for rare-earth-activated materials and much of today's cutting-edge optical technology and emerging innovations are enabled by their unique properties. In many of these applications, interactions between the rare-earth ion and the host material's electronic states can enhance or inhibit performance and provide mechanisms for manipulating the optical properties. Continued advances in these technologies require knowledge of the relative energies of rare-earth and crystal band states so that properties of available materials may be fully understood and new ...; Download File | View full details
