The structure belongs to the monoclinic system, space group P21/n with Z = 4, α = 7.181（3）, b = 13.059（5） and c = 9.730 （4） ？. It is described as a three-dimensional （3D） architecture made up of [P4O12]4- anionic spiral chains and HoO8 polyhedra by corner-sharing. The 8-coordinated sodium atoms are located in infinite tunnels. The results of EDX and IR spectrum are in good agreement with the crystallographic analysis. In addition, NaHo（PO3）4 exhibits visible light emission in the solid state at room temperature.展开更多
