Tetrahedral coordinated Mn(V) in Ba3V2O8 with varied stoichiometry as thermally stable turquoise to dodger blue inorganic pigments

Hydrothermal and anion exchange synthesis of Mn(v)-doped Ba5(PO4)3Cl nano-apatite toward NIR-II temperature sensing

“…8,25 Furthermore, the absorption band of MnO 4 3− at 700–870 cm −1 aligns with the literature findings. 17,26 Fig. 2d depicts the Raman spectra measured from 100 to 2500 cm −1 , showing a prominent peak at 888 cm −1 attributed to MnO 4 3− incorporation.…”

“…Mn 5+ existing as MnO 4 3− anions can be effectively and steadily incorporated into oxides containing MO 4 (M = P, V) tetrahedra. 16,17 Therefore, it is a great challenge to stabilize the Mn 5+ activator in a solid using the solid-phase method, and it is even more difficult to synthesize the Mn 5+ -activated nanoparticle in which the soft-chemical method is applied.…”
