Abstract

The NIR-emitting optical centers in Bi2O3-doped MgO–Al2O3–SiO2 glass were shown to be bismuth dimers formed in a reversible endothermic redox chemical reaction. The reaction enthalpy and the effective dimer charge were determined. It was also brought out that the red (∼720 nm) emission band originates from the centers that are quite different from IR-emitting ones.
