Concentration-dependent anomalous broadband down-and upconversion luminescence of Yb3+/Mn2+ codoped barium octaborate have been demonstrated. Upon ultraviolet (UV) excitation, dual Gaussian emission bands depend on the Mn2+ concentration located at 550 and 656 nm were respectively ascribed to the Mn2+ pairs and single Mn2+ ion. Moreover, abnormal broadband upconversion luminescence at room temperature in BaB8O13:Yb3+, Mn2+ under near-infrared (NIR) excitation of Yb3+ at 976 nm was demonstrated by the cooperative sensitization luminescence process. The experimental results could provide new insights into developing lighting and display systems, and biomedical imaging. (C) 2013 Elsevier B. V. All rights reserved.
