Abstract
It was shown that broadband near infrared fluorescence in recently discovered in Bi-doped glasses is not specific to Biions. Germanate glasses doped with different 6p (Bi, Pb) and 5p (Sn, Sb) ions (co-doped with Al) exhibit similar behavior. The centers can be characterized by 4 peaks in the excitation-emission plots. The decay of fluorescence (excited with short laser pulse at 800 nm and 532 nm) has complex behavior. The components of the decay are in the nsto ms- range and they have different temperature dependences. To our opinion, existing models of optical center suggested earlier should be revised to agree with new data.
