Abstract

The visible spectra of Co²⁺ in both polymer-like and network-like sodium phosphate glasses were studied at elevated temperatures. A plot of the Co^{2+ 4}A₂ → ⁴T₁(P) absorption at 580 nm versus temperature showed a discontinuity at a temperature above the glass transition in each case. The discontinuity was attributed to an increase in non-bridging oxygens caused by thermal disruption of branching PO₄^-3 units.
