摘 要：<正>We report on broadband infrared emission of bismuth-doped RO-B2O3（R=Ca,Sr,Ba） glasses. Glass samples are prepared under various conditions by a conventional melting-quenching method and the luminescence properties in infrared wavelength region are investigated,No apparent infrared luminescence is observed in the SrO-B2O3 and BaO-B2O3 prepared in air,while glasses prepared in reducing atmosphere exhibit a broadband infrared luminescence peaking at 1300 nm with a full width at half maximum（FWHM） of about 200 nm when excited by an 800 nm laser diode.A mechanism was proposed to explain the observed phenomena. The presence of low valence bismuth,probably Bi+,is responsible for the broadband infrared emission.
