Laser-Induced Fluorescence Line Narrowing of Eu3+ in Lithium Borate Glass
Laser-induced fluorescence line narrowing has recently been used to investigate the local environment and interactions of paramagnetic ions in glass. Since the resulting spectra are sensitive to structural modifications, this technique was applied to study lithium borate glass. In alkali borate glasses, the relative numbers of BO3 triangles and BO4 tetrahedra and the existence of subliquidus immiscibility are dependent upon the mole fraction of alkali oxide. Structural changes associated with these properties are, in principle, detectable using the approach of fluorescence line narrowing. Evidence of these effects are presented in this paper.
