Journal ArticleDOI
Multiphonon relaxation of rare-earth ions in oxide glasses
TL;DR: In this paper, a series of oxide glasses were investigated for the nonradiative decay of excited rare-earth ions by multiphononon emission and the results showed that the strength of the ion-phonon coupling was approximately equal for all glasses.
Journal ArticleDOI
Multiphonon relaxation of rare-earth ions in beryllium-fluoride glass
C. B. Layne,M. J. Weber +1 more
TL;DR: In this article, the authors investigated the relaxation of excited electronic states of rare-earth ions by multiphonon emission in a beryllium-fluoride glass and measured the decay rates from the transient fluorescence following pulsed laser excitation of selected states.
Journal ArticleDOI
Spectroscopic properties of excited states of ions in glass measured using laser-induced fluorescence line narrowing
TL;DR: In this article, laser-induced fluorescence-line-narrowing techniques are extended to measure site-to-site variations in the spectroscopic properties of excited states of optically active ions in glass.
Journal ArticleDOI
Nuclear-magnetic-resonance studies and molecular-dynamics simulations of the structure of sodium fluoroberyllate glasses: Evidence of non-tetrahedrally-coordinated beryllium.
TL;DR: In this article, the authors used NMR measurements of two beryllium fluoride glasses: a simple binary glass and a NaF-ensuremath{\cdot}{2\mathrm{B}mathm{e}{e}.
Journal ArticleDOI
Vibronic spectrum of Gd/sup 3 +/ in BeF/sub 2/ class
D. W. Hall,M. J. Weber +1 more
TL;DR: Vibronic sidebands associated with the transition of Be${\mathrm{Gd})3+$ in Be${F}}_{2}$ glass are observed with the use of line-narrowed fluorescence techniques as mentioned in this paper.
