摘要：

Luminescence properties of CaAl2O4: Eu2+, Mn2+ have been investigated as a function of coactivator concentrations. We have discovered that two main emission bands attributed to Eu2+ and Mn2+ under UV light excitation via an efficient energy transfer process. With fixed Eu2+ doping concentration, the emission color varies with increasing Mn2+ content. Finally, white light is realized by combining the Eu2+ and Mn2+ emissions. In addition, CaAl2O4: Eu2+, Mn2+ exhibits a strong absorption in ultraviolet spectral region which may find utility as a single-component UV-WLEDs. (C) 2013 Elsevier Ltd. All rights reserved.
