A synthetic molecular strategy for in-situ growth of CePO4 as a transition layer has been proposed to obtain rare earth sulfides with satisfactory chromaticity and stability. The transition layer significantly reduces lattice spacing differences and oxygen activity on the interface, resulting in excellent chromaticity and stability for the core-shell structure.
To obtain rare earth sulfides with satisfied chromaticity and stability for diverse applications in the field of pigment, a harnessed synthetic molecular strategy for in-situ growth of CePO4 as an interlayer between core Ce2S3 substrate and the outer SiO2 layer is proposed. High-angle annular dark-field scanning transmission electron microscope (HAADF-STEM), electron paramagnetic resonance (EPR), and Raman analysis reveal that the tran-sition layer CePO4 significantly reduces the lattice spacing differences and reduces the oxygen activity on the interface, resulting in excellent chromaticity (L* = 51.9, a* = 45.0, b* = 30.0) and stability for gamma-Ce2S3@Ce-PO4@SiO2. These insights will advance the fundamental knowledge of core-shell crystal engineering and enable new ways to promote the application of rare earth sulfides.
