【 摘 要 】

Developing a material with a new morphology is very important for improving the functional performance and finding new applications. Monoclinic samarium oxysulfate (Sm2O2SO4) nanoplates were first prepared using a hydrothermal process followed by a post‐annealing treatment of an as‐synthesized Sm2(OH)4SO4·2H2O plate at 450 °C. The fundamental physicochemical properties were examined by scanning electron microscopy, high‐resolution transmission electron microscopy, Rietveld X‐ray diffraction crystallographic data analysis, thermogravimetric analysis/differential scanning calorimetry, Fourier transform‐infrared spectroscopy, Raman spectroscopy, ultraviolet–visible‐NIR absorption, and X‐ray photoelectron spectroscopy.
