A new series of Cd3BPO7:M (M = Ce3+, Tb3+, Mn2+) phosphors have been synthesized and characterized using X-ray powder diffraction as well as excitation and emission spectroscopy. Based on the Cd3BPO7 host, the singly doping Ce3+, Tb3+ and Mn2+ yield the blue, green and red-emitting phosphors respectively under the irradiation range from 270 to 300 nm UV. By appropriate tuning of Tb3+ or Mn2+ activator content, the emission color of the Cd3BPO7:Ce3+/M (M = Tb3+ or Mn2+) phosphors can be changed from blue to green or pink, respectively. Under UV excitation, the mixture of the as-prepared blue, green and red phosphors yields the warm white light, which exhibits their potential application as UV-convertible phosphors for WLEDs.
