Abstract
AbstractA new phosphor Sm(IO3)3·2H2O was synthesized under mild hydrothermal conditions. The structure was confirmed by single‐crystal X‐ray powder diffraction analysis. It crystallizes in the triclinic system with space group P$\bar{1}$ (No.2), a = 7.1570Å, b = 7.4306Å, c = 10.6367Å, α = 95.205°, β = 104.844°, γ = 109.958°. Some characterizations were performed such as Fourier transform infrared spectroscopy (FTIR), powder X‐ray diffraction (PXRD), thermogravimetric and differential thermal analysis (TG‐DTA), and luminescence spectroscopy. The overall structure of the title compound is two‐dimensional. The adjacent iodate layers are further linked with each other by hydrogen bonds to form a three‐dimensional supramolecular network. The luminescent properties of Sm(IO3)3·2H2O were studied, the exhibit tunable emission spectra by means of heating treatment.
