Novel phosphors BaGd2Si3O10:RE2+/3+ (RE = Eu or Ce) were designed and prepared by a solid state reaction. The crystal structure was characterized by X-ray diffraction. The optical band gap was estimated by the diffuse reflectance spectrum. The photoluminescence properties were investigated and the results indicate that under ultraviolet light excitation, BaGd2Si3O10:Eu3+, BaGd2Si3O10:Eu2+ and BaGd2Si3O10:Ce3+ phosphors show red, green and blue emission, respectively. The trichromatic emission available by doping different rare earth ions proves that BaGd2Si3O10 should be a promising host material for phosphors in white LEDs.
