A novel Dy3+-doped NaBaBO3 white-emitting phosphor has been prepared by high temperature solid-state reaction method. The phase structure and luminescence properties of NaBaBO3:Dy3+,K+ samples were investigated. Photoluminescence results show that the as-prepared samples could be effectively excited by near-ultraviolet (NUV) light and generate white light emission due to the 4F9/2 → 6H15/2 (blue) transition and 4F9/2 → 6H13/2 (yellow) transition of Dy3+ ions, respectively. The optimum doping concentration ...
