A series of phosphors (Sr0.995-x-y-zCaxBayMgz)(2)SiO4:0.01Eu(2+) (0 <= x <= 0.45, 0 <= y <= 0.015, 0 <= z <= 0.35) were synthesized by solid state reaction. Their phase compositions and photoluminescent properties were investigated in detail. The X-ray diffraction analysis indicates the impurity phase of SrSiO3 is formed only when z >= 0.25. A photoluminescence investigation shows, with x increasing the emission spectra of the phosphors (0 <= x <= 0.45, 0 <= y <= 0.015, z = 0) obviously red-shift, the corresponding color tones shift from yellow to orange yellow and their CCTs reduce from 2875 to 2237 K. All the results are beneficial for the phosphors to combining blue light-emitting diode chips to generate warm white light. Besides, the thermal stability of the phosphor (x = 0.36, y = z = 0) is enhanced by doping Ba2+, due to the greater activation energy for the compounds containing barium. (C) 2014 Elsevier Ltd.
