%X The luminescence of unusual divalent bismuth (Bi2+) in BaB8O13 is reported. The emission band with maximum peak at 592 nm corresponds to the 2P3/2 2P1/2 transition of Bi2+ in the matrix and the excitation spectrum with two bands peaked at 470 and 580 nm respectively corresponds to two split crystal-field levels of 2P3/2 state. The small Stokes shift (-350 cm-1) reflects the rigid structure of the host for the Bi2+ ions.
