• Creation of bismuth-containing near-infrared (NIR) luminescent centers by synproportionation reaction of Bi super(3+) and Bi super(0) was demonstrated in borate and phosphate glasses. This finding is discussed in the light of low-valence nature of bismuth NIR-luminescent centers. The experimental data is consistent with the hypothesis of univalent Bi super(+) (and, possible, subvalent cluster Bi ions) as a source of NIR luminescence. The dependence of Bi luminescent centers stability on oxoacidity of glass melts was discussed.
