摘      要：Non-toxic rare earth(RE) composite materials are promising and active in optoelectronic fields,such as *** this work,Na ions doped γ-Ce_(2) S_(3) pigments were synthesized by solid-phase vulcanization and followed by in-situ synthesis to prepare an outer layer of CePO_(4) *** characterizations of X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),solid state nuclear magnetic resonance(NMR) indicate that Na-dopedγ-Ce_(2) S_(3) and CePO_(4) uniformly and tightly coated core-shell structure was successfully *** thermogravimetric analysis(TG) and reflection spectrum(RS) reveal that the CePO_(4) coating significantly improves the colorant and thermal stability performance of γ-Ce_(2) S_(3) .The excellent color quality of γ-Ce_(2) S_(3) @CePO_(4)(L*=45.16,a*=55.94.b*=44.53) is achieved and the red color(L*=43.82,a*=49.79,b*=38.04) is still retained even if the sample is heated in air at 400℃ for 30 min.
