We investigated infrared luminescent phenomena in bismuth lanthanum borate glasses. In bismuth lanthanum borate glasses, the absorption peak was observed at 460 nm. The absorption peak was observed only when the glass was melted in Al2O3 crucible, whereas no peak was seen in the case of Pt crucible and the case of Al2O3 doped sample melted in Pt crucible. The infrared emission peak was observed at 1300 nm excited at 800nm. Life time at 1300 nm was 56.7 μs. We suggested that the absorption and infrared emission have been associated with pentavalent Bi ions in the glasses. It was estimated by La 3d XPS spectra and ESR spectra.
