Abstract
In this paper, Sm3+-doped Ca6BaP4O17 phosphors were synthesized via a conventional solid-state reaction method. Orange-red emission was observed from these phosphors under near-ultraviolet (UV) excitation at 405nm. The luminescence properties of the obtained phosphors were characterized. The Ca6BaP4O17:Sm3+ phosphor can be efficiently excited by near-UV and blue light, and their emission spectrum consists of three emission peaks, at 567, 602, and 650nm, respectively. The thermal stability of Ca6BaP4O17:Sm3+ phosphors was investigated systematically and corresponding mechanisms were proposed. Based on the results, the as-prepared Ca6BaP4O17:Sm3+ phosphors are promising orange-red-emitting phosphors for near-UV-based white light-emitting diodes.
