Structure and interactions of the core and shell phases. (a) Spatial-resolved micro-Raman spectra of the crystals obtained at different stages of the morphology evolution. Micrographs of the (b) MC and (c) CS. (d) and (e) Cross-section of CS showing the (d) shell phase and the (e) core phase. (f) TGA plots of crystals obtained at different evolution stages. (g) and (h) FTIR spectra of crystals obtained at different stages. The green region in (g) highlighted the —OH stretching of water molecules, and the blue and purple regions in (h) highlighted the H—O—H symmetric bending vibrations and C—N stretching, respectively.
