Eu2+, Dy3+ co-doped Sr2Si5N8 red phosphors were prepared using a sol–gel-nitridation method at a lower temperature comparing with traditional solid state reaction. Effects of synthesis process, Eu2+ and Dy3+ doping concentration on the crystal structure and luminescence property of as-prepared phosphors were investigated. X-ray diffraction patterns indicated that all Sr2Si5N8:Eu2+, Dy3+ phosphors...
