Role of Er3+ and Bi3+ ions on thermal and optical properties of Li2B4O7 glasses: Structural correlation
TL;DR: In this paper, the effect of Er2O3/BiCl3 on their physical, thermal, and optical properties was investigated and it was shown that the optical properties of both the investigated glass systems exhibit composition dependent trends and the properties are critically dependent on polarizabilities and ionicity of the dopant ions.

Theoretical investigations on the EPR parameters and local structures for V4+ in alkali niobium borate glasses
TL;DR: In this paper, the perturbation formulas of EPR parameters for tetragonally compressed octahedral 3d1 clusters were derived from the quasi-linear concentration variations for covalency factor N, tetragonal compression ratio ρ and core polarization constant κ with only three adjustable coefficients.
